Be it razor holders reordering blades at the push of a button or refrigerated containers being monitored on their journey between continents – the IoT (Internet of Things) already connects many things; a trend that seems to be increasing by the day. Who knows how many it will eventually be? According to forecasts, between 200 million and 100 billion devices will be connected through the Internet of Things by 2020 alone.

The overall market for AC/DC and DC/DC commercial switch mode power supplies (C-SMPS), which excludes consumers and uninterruptible power supplies (UPS), is estimated to be in a range of 22 to 25 billion US Dollars.

This level has been stable for more than five years and from an outsider’s point of view, could be perceived as a very static industry with very moderate growth index.

QCA4010 & DNSA-MP1

CODICO PRESENTS THE NEW HOSTLESS WI-FI SOLUTIONS FOR IOT APPLICATIONS With the recent hype and the successfull releases of IoT products in the last years, many companies are put under big pressure to follow this hype and to take the initiative of coming up with own IoT products or to extend the existing product portfolio respectively.

With the increasing number of nodes connected to the Internet, also the demand for low cost solutions with reduced BOM cost has increased. One way to overcome this, is the integration of the application MCU, networkprocessor and Wi-Fi radio in one IC. The so-called SoC (System on Chip) allows the implementation of a complete IoT application on a single device without the need of an external MCU. As no external MCU is required, this kind of operation is named hostless mode. The new QCA4010 from Qualcomm follows this approach and provides also special low power features and wake up scenarios .Wistron, as an ODM partner, has released a WiFi module (DNSA-MP1) that is based on the QCA4010.

The Qca4010 integrates an Xtensa cpu @ 130 Mhz from Tensilica that is responsible to provide all ip services and to manage all wi-fi links. The Qca4010 provides no internal flash, but sraM and roM. Therefore the network processor code, system configuration and persistent data sets are loaded from external serial flash memory into the internal sraM before execution. The application code is executed on the same cpu and memory ressources like the network processing code. Because the

of the Xtensa cpu together with the clock speed of 130 Mhz provide sufficient calculation power to overcome this demand.

To fulfill the different application memory requirements in the ioT world, the Qca4010 is released in two sraM versions. The smaler version integrates 1 MB sraM, whereas ~400KB is reserved for application code. The bigger version provides 1.5MB, which allows the integration of ~800KB application code.

QCA4010 System Architecture sesnor measurement, actor control and data processing handled by the application is normally done before a wi-fi link is established for data snychonisation, there is no bottlneck from the processing point of view. so in the most ioT applications, network and application processing is done in a time division manner by the cpu.

But even if there is a demand to process both at the same time, the performance-rich 32 bit architecture

in order to reduce power consumption to a minimum, the Qca4010 provides an integrated power Management unit (pMu) that controls different power modes based on the following techniques: • Gating Clock: not required function blocks are disconnected from the clock network in order to prevent charge-reversal currents of parasite capacities.

IoT APPlICATIONS

• Shut down High Speed Clock: when the high speed clock network is not needed, it can be entirely disconnected, including external pulse sources such as oscillators.

• Reduction of the voltage level: The voltage levels of individual blocks can be reduced in order to keep the static leakage currents low. a minimum voltage guarantees a short wake-up time and maintains the data contents of all registers and of the volatile memory.

The different low power modes are also supported by a low speed clock network (32.768 khz) and a wakeup manager unit.

The low speed clock network is required to run the state machine and sleep timers. The wakeup manager resumes operation by detecting internal and external trigger signals. for example, in supend mode it detects a wake up signal at a pin or from the internal sleep timer, after a predefined time has passed. in this mode it manages also a small raM that stores state information. further modes like power down (~9µa), sleep and hosT_off extend the range of configurations and allows a fine power tuning of an ioT application. But even in network operation, when the cpu is running at high speed clock and a wi-fi link is operating, the user profits from the low power features like green Tx power saving mode and low power listen mode supported by the radio.

The Qca4010 provides many different interfaces that are required in typical ioT applications. for the measurement of analog sensors, a 12 bit adc with 8 channels supports 400ksps for multiple channels and 1 Msps for single channel operation. 8 independent 18 bit resolution pwMs with 8 bitclock prescaler are also available for e.g. motor control and lighting. for serial communication the user can chose from hs uarT (3 Mbps), low speed uarT, spi, i2s or i2c as well. The following list gives an overview about the features: • • • • • • • • •

• 8 channels 12-bit accuracy adc, maximum sampling rate is 400 Ksps for multiple channels and 1 Msps for single channel.

• 8 18-bit resolution pwM with 8-bit clock prescaler • 9×9mm drQfn-116pin • case temperature range: 0°c to 85°c (standard); -45°c to 115°c (extended) for dual band application (2.4ghz & 5ghz), Qualcomm offers the Qca4012, which has exact the same system architecture and features like the “small” brother Qca4010, but provides just an additional 5ghz radio path.

Therefor both parts are available in the same 9mm × 9mm × 0.9mm dual-row Quad flat pack nolead (drQfn) package that includes a ground pad for improved grounding, mechanical strength, and thermal continuity.

Moreover both parts are even pin compatible. But it should be mentioned that the concurrent mode is not supported by the Qca4012 as only one wifi link (2.4ghz or 5ghz) can be served at a time. anyhow, both devices (Qca4010 & Qca4012) support rx diversity in the case that two rx antennas are connected to the devices.

Quaclomm is an ic but not a pcB module supplier. Therefore Qualcomm works very closely with odM partners like wistron, which manufacture and sells wi-fi modules based on the original reference designs/ modules from Qualcomm. in case of Qca 4010, wistron offers a module with the part number dnsa-Mp1. Mp1 is Qualcomm’s internal name for the Qca4010 reference module. wistron has extend this part number with the prefix dnsa- to create an internal one. documentation, sw and technical support is provided by Qualcomm,

whereas wistron provides the hw and the test reports based on the module name dnsa-Mp1.

WIRELESS TECHNOLOGIES FOR IoT NETWORKS

autor: Schaal Anja, rutronik

Long Range Wireless Solutions Be it razor holders reordering blades at the push of a button or refrigerated containers being monitored on their journey between continents – the IoT (Internet of Things) already connects many things; a trend that seems to be increasing by the day. Who knows how many it will eventually be? According to forecasts, between 200 million and 100 billion devices will be connected through the Internet of Things by 2020 alone.

What is certain is that IPv6 has raised the number of supported IP addresses from roughly four billion to over 340 sextillion (a figure with 37 (!) zeros).

The supporting pillars are therefore in place. Whoever seeks to build upon them must focus on wireless technology.

An overview of current long range IoT solutions is obviously an extremely helpful resource.

long range ioT wireless technologies form the basis for a lPWAN (Low Power Wide Area Network). in these types of networks, end devices with low energy consumption – typically sensors – are connected to gateways which transmit data to other devices and network servers. The network devices assess the received data and control the end devices. accordingly, the protocols are specially designed for long-range capabilities, lowpower devices, and reduced operating costs.

CEllUlAR WIRElESS / lTE for a long time, cellular wireless technologies had a monopoly position in long-range applications which can connect a device directly to the internet without a gateway.

Thanks to the well-established infrastructure of base stations worldwide, end products only require a siM card to communicate with the cloud. after successful initialization and registration with the network provider, data can be sent and received. further development of cellular wireless technologies in the past generally focused on increasing data transmission rates. lTe advanced, for instance, now enables a transmission rate of up to 3.9gbps in the downlink and 1.5gbps in the uplink. however, most things in the ioT do not transmit such huge amounts of data, the majority of them require less than 100bpm. The focus of successful communication technology is therefore on long ranges, reliable communication, and low power consumption for extended battery life. low data rates obviously have a positive effective on power consumption.

lTE-M with this aim in mind, 3GPP (Third Generation Partnership Project), whose scope is to further develop cellular wireless standards (gsM, uMTs, lTe), has created the lTe-M standard. it is also referred to as lTe-MTc (Machine Type Communications). lTe-M transmits in the licensed sub-ghz band at between 700Mhz and 900Mhz. The downlink and uplink data rates are roughly 1Mbps. The low-power consumption approach should help to extend the battery life of battery-powered end devices up to between 10 and 20 years. a further positive aspect of lTe-M is the excellent coverage it provides, as lTe-M uses the existing cellular wireless infrastructure. an added advantage for providers is that lTe-M operates on the well-known licensed spectrum. it is, therefore, extremely safe and robust and also ideal for services with high quality requirements. one disadvantage of lTe-M is the high costs for utilizing licensed cellular wireless networks. in this case, each end device requires its own siM card which results in additional installation and maintenance costs. in addition, there are running expenses which, on average, are significantly higher than those for comparable technologies. Moreover, the current siM card service for lTe-M is comparatively complicated. help may be provided in the future by the esiM card (embedded siM card). as the name suggests, it is embedded in the end device and can, when swapping provider, be easily reprogrammed without having to open the actual device.

IoT APPlICATIONS

The xe910 family from Telit, for example, is ideal when transitioning to newer cellular wireless generations. Modules for gsM, various uMTs versions, and lTe are currently available, and the manufacturer has already announced modules for lTe-M. devices can be upgraded efficiently and effectively with the modules thanks to the identical form factor. on top of this, Telit additionally offers added value services, e.g. specific siM cards and tariffs for industrial applications.

Sigfox sigfox is a tailor-made solution for long ranges (30 - 50 km in rural areas, 3 - 10 km in urban areas), low data rates (12 bytes per message, max. 140 messages a day per end device), and preferably low power operation. sigfox uses the sub-ghz band (868 Mhz in europe) and employs BpsK modulation with ultra-narrowband technology. end devices equipped with sigfox technology transmit data to sigfox base stations which then forward the data to sigfox servers. This is where the data are processed before the results are sent back to the respective end devices for visualization. This means: data are managed by sigfox on in its own cloud servers. unlike lTe, the sigfox infrastructure is still under construction. The company works with large network operators around the globe, although it continues to deploy and operate its own networks in various regions, e.g. in france and the usa. sigfox currently offers service coverage in france, portugal, spain, the netherlands, and the uK. The ioT specialist is further ramping up its rollout plans for Belgium, denmark, germany, ireland, italy, luxembourg, and the usa: in the usa alone, the frenchbased company plans to expand from 10 to 50 cities in just six months. nevertheless, the technology is not yet recommendable for country-wide or international projects. a siM card is not required for sigfox. The price depends on how many messages are

sent per day and the volume of these messages. customers generally pay between one and ten euros a year to keep an individual end device active.

Transmitter and transceiver solutions for sigfox are offered, e.g., by Microchip atmel's aTa8520 family. socs (system on chip) come with integrated dBpsK modulation and sigfox protocol stack. Their sigfox id, pac code, and encryption key are stored and secured inside the chip, safe from extraction. To enhance flexibility, the aTa8520 can be connected to every type of microcontroller. The le51-868s family from Telit comprises dip and sMd module solutions that can be plugged and soldered respectively. They operate in the 863 Mhz to 870 Mhz band with both the Telit proprietary protocol and the sigfox gateway. loRa lora is very similar to the sigfox technology: lora also uses the sub-ghz band (868 Mhz in europe), achieves similar ranges (up to approx.15 km), and is very economical due to low data rates ranging from 0.3 to 22 kbps. in contrast to sigfox, lora utilizes chip spread spectrum technology to flexibly set the ratio between bandwidth and bitrate.

The lora alliance was established in 2015 to standardize and further develop lora.

Besides the lora developer semtech, numerous chip and module manufacturers, software businesses and network operators are now members of the lora alliance, including, e.g. Microchip and sT Microelectronics. anyone wanting to equip their end products with lora has to pay an annual license fee of $3,000 to the lora alliance. There are no other fees payable on top of this, and lora, just like sigfox, does not require a siM card. in terms of infrastructure, the situation for both newcomers is about the same: The lora alliance members are working intensively on expanding coverage, particularly in europe and the usa, but also in large russian cities. Thanks to an interactive net-

work, each user can help to expand the lora infrastructure. and users who do not want to wait for improved coverage can also set up a private network using lora technology – if the application enables it. lora module solutions from Microchip are available for both the european (rn2483) and us market (rn2903). The highly integrated modules contain the microcontroller unit, crystal, eui-64 node identity serial eeproM, radio transceiver with analog front end, and matching circuitry. for development purposes, the manufacturer offers specific boards and a full gateway development kit.

NECk-AND-NECk RACE compared to lTe-M, both lora and sigfox offer cost benefits: at present, the hardware for a module costs about €10. added to this is the $3,000 annual license fee for lora, while sigfox users can expect to pay between one and ten euros a year for each end device. The hardware costs alone for lTe-M are much higher than those for sigfox and lora, and added to this are the running expenses for the siM cards and the costs for replacement items.

The lora and sigfox wireless modules for end devices ensure very low power operation and can transmit over large distances with strong in-building penetration characteristics. The biggest stumbling block for both technologies is, however, the infrastructure, which is still a work in progress. it has turned into a neck-and-neck race between lora and sigfox, and it will be interesting to see who wins – or maybe a new competitor will enter the fray. The ability to allow the creation of private networks is obviously particularly advantageous to lora. it might not be suitable for every application, but ensures lora a certain degree of independence no matter what the outcome of the race. But data communication using cellular wireless technology continues to offer plenty of opportunities. for instance, nordic semiconductor, a leading provider of ultra-low power wireless connectivity, announced the development of the nrf91 series with low power lTe technology in July of this year. The company's roadmap includes highly integrated solutions for the forthcoming 3gpp release 13 lTe-M and nB-ioT cellular technologies, a brand new type of narrowband communication with “things”.

Zhang feng from Microchip Technology explains how to build a lowenergy digital pedometer.

ONE STEP AT A TIME wearable technology has never been in the news as much as it is today. The march of the wearables – a generic term for electronic devices worn on the body that monitor how the body is functioning – looks unstoppable. leading this trend are activity trackers, measuring the numbers of steps taken, encouraging the wearers to engage in proper daily exercise that can reduce blood pressure and body mass index.

Bracelet-type activity trackers combining step counters and Bluetooth low energy are becoming popular as motivation tools for those wanting to improve their physical activity and health. a digital pedometer is a portable electronic device that counts each step a person takes by detecting the motion of the person’s

body with an accelerometer. such a device can be built using an 8bit microcontroller, a Bluetooth low energy module and a digital triaxial accelerometer. This demonstration device can be worn on the wrist as with a bracelet or watch. The on-board Bluetooth le module allows the pedometer to communicate with a smartphone or tablet on which the user’s exercise progress can be tracked. figure 1 shows the block diagram of such a pedometer using a Microchip pic16lf1718 microcontroller, Microchip rn4020 Bluetooth le 4.1 module, Bosch sensortec BMa250e digital triaxial accelerometer and cr2032 3V coin lithium battery.

OPERATION The 10bit accelerometer detects the motion of the wearer. firmware in the microcontroller contains a step-detection algorithm developed by Bosch sensortec. a step-detection function in this library is called periodically by the user application.

The microcontroller reads the acceleration data along the x, y and z axes from the accelerometer via an i2c interface when the stepdetection function is called. The step-detection function then analyses the accumulated acceleration data and uses pattern recognition to determine the number of steps taken.

The accumulated number of steps can be shown on a three-digit seven-segment led display or, via Bluetooth le, on an application running on a smartphone or tablet. figure 2 is a flowchart that show the process flow of the pedometer demo. The Bluetooth le module with which it is paired complies with the Bluetooth 4.1 core specification and supports 13 public profiles and 17 public services

DIGITAl PEDOMETER based on the gaTT general attribute profile. among the supported public profiles, four are health based – heart rate monitor, health thermometer, glucose meter and blood pressure monitor.

The module also supports a user-defined private profile or service that can precisely fit the user’s application. in this case, the demo defined a private service for the pedometer application.

front and back of the pedometer demo board

Figure 3

Figure 2 firmware process flow of the pedometer demo all configurations are saved in the on-board non-volatile memory of the Bluetooth le module so that users need to set up the module only once. The microcontroller activates the module when the Bluetooth le communications are enabled by pressing the onboard button. The module then becomes pairable with a smartphone or tablet. The microcontroller periodically sends the step number to the module via a uarT interface after successful pairing. The module then transmits the step number to the paired mobile device, where a compatible Bluetooth le application can be used to display the step number. however, a companion application may not be needed if the device has apple healthKit installed, a feature for ios 8 and later that adheres to the Bluetooth le gaTT specifications. This means that medical devices such as heart rate and blood pressure monitors, thermometers, and glucose meters that are built with the rn4020 module will be supported natively by apple healthKit. so instead of developing a companion application, device manufacturers can allow apple healthKit to control the device or accessory automatically when it is paired with the Bluetooth le module. one button provides quick function control to the pedometer demo via the interrupt-on-change (ioc) interface. To turn the led display on or off, the user needs to press the button and quickly release it within one second. To enable or disable Bluetooth le communications, the user needs to press the button down and hold it for more than one second but less that four seconds. holding the button down for more than four seconds and then releasing it will zero the step number. www.international.electronica-azi.ro

POWER power for the pedometer demo comes from a single 3V lithium coin battery. The led displays are automatically turned off after ten seconds to save power. The baud rate of the uarT communications is set to 2400kbit/s so that the Bluetooth le module can remain in deep sleep mode when there are no uarT data communications. if there is no motion for 16s, the accelerometer will send a no-motion interrupt to the microcontroller via the ioc interface. when the no-motion interrupt occurs, the microcontroller reconfigures the accelerometer to high-g interrupt and puts it into a low power mode, after which the microcontroller itself goes into sleep mode so the overall system is consuming the lowest possible power. during the low power mode, the accelerometer is periodically switching between a sleep phase and a wake-up phase. while in the sleep phase, the whole analogue circuit of the accelerometer is powered down. in wake-up phase, the accelerometer works normally and the high-g interrupt function is running to determine when to wake up from the low power mode.

The accelerometer generates a high-g interrupt to wake up the microcontroller when the wearer’s motion is over the pre-set threshold for a high acceleration event, such as walking, picking up the pedometer, or waving or rotating the pedometer in the air.

The pedometer resumes normal operation after waking up.

CONClUSION This article has shown how to build a pedometer than can communicate via Bluetooth le for evaluation and development purposes. it is not intended for medical, diagnostic or treatment use, but can be a useful device for people keen to monitor and increase the amount they exercise.

Together with the event system, that allows peripherals to communicate without using the cpu, applications can be optimized at a system level. This lowers power consumption and increases throughput and system reliability. pic Microcontrollers with core independent peripherals take 8-bit Mcu performance to a new level. with a number of on-board modules designed to increase capability in any control system, these Mcus represent the best value in embedded design.

CORE INDEPENDENT PERIPHERAlS kEY ATTRIBUTES Self-Sustaining once initialized in a system, core independent peripherals can provide steady-state closed loop embedded control with zero intervention from the Mcu's core. The cpu can then be idled or put into sleep mode to save system power.

Significant Savings By taking the load off the cpu, core independent peripherals allow smaller, lower power pic Mcus to perform extremely complex tasks, such as high power lighting control and communication. in addition, significant BoM cost savings can be realized by replacing off-board discrete components with these integrated peripherals. | 1/2017

CPU free core independent peripherals are smartly interconnected to allow near zero latency sharing of data, logic inputs, or analog signals without additional code or interruption of the cpu. This frees the cpu to perform other system tasks and reduces flash memory consumption.

PIC & AVR MCUs

each peripheral has been crafted to work both individually and in tandem with other parts of a Mcu to enable commonly used tasks with minimal supervision from the core processor. This allows a pic and aVr Mcu to support as many system functions as possible, while minimizing the use of external components and the need for power-hungry resources. our function enablement approach helps reduce system cost and can increase an end product’s performance and robustness. core independent peripherals are available in both 8 bit microcontrollers from pic10, pic12, pic16, pic18 families, as well in aTmega aVr series.

POWER DESIGN

THE FASCINATING WORLD OF THE POWER SUPPLY INDUSTRY author: Patrick le fèvre, chief Marketing and communications officer Powerbox

The overall market for AC/DC and DC/DC commercial switch mode power supplies (C-SMPS), which excludes consumers and uninterruptible power supplies (UPS), is estimated to be in a range of 22 to 25 billion US Dollars. This level has been stable for more than five years and from an outsider’s point of view, could be perceived as a very static industry with very moderate growth index. This perception is amplified by a general feeling that the power supply industry reached such level of maturity, nothing will really happen, which in fact is not the case. Despite the steady top number, the C-SMPS industry is extremely dynamic, adjusting to market changes, new regulations, emerging new technologies and in permanent transformation, developing products and power solutions for early stage new technologies (e.g. 5G, Industry 4.0) or even not existing.

SEGMENTS TRANSfORMATION it is not possible to go into details for every segment but there is one, which has had a major influence to all other, the Telecom/ datacom segment. for decades, the Telecommunication segment has been predominant and one of the main technology driver for innovations within the power industry. we all remember the evolution in power distribution, moving from centralized-power to de-centralized power, which has been then adopted by

other industries, becoming the worldwide power-architecture in all segments from industrial to defense. as well for the introduction of digital power technology, which is now used in many products operated in non-telecom segment. all those technology evolutions have been driven by the need to make telecom equipment more energy efficient, to reduce energy consumption and carbon footprint, but as well possible to integrate, what used to be the size of building in the eighties, down to a chipset nowadays. integrating, what used to be a central telecom office down to a chipset has had a big impact on the volume of power modules consumed by this industry but as well how the power distributed and optimized. at the peak days in year 2000, the worldwide production of 5 to 20w board mounted dc/dc converters for the telecom industry was close to the 35 million units, which, for similar category of products consumed in the telecom industry is estimated to be below 6 million in 2017. we all know that the telecom market has reached a certain

level of saturation but they are other reasons explaining this impressive decline in volume: higher level of integration and increase use of discrete solution.

Higher level of integration Migrating from voice to data, the telecom industry rapidly reach a point of integration with the datacom industry to become the information, communication and Technology (icT). at that point of time, both industry boosted the development of new generation of signal processors and other complex data-management asics requiring higher power dc/dc (e.g. intermediate Bus converters) with localized step down conversion achieved by point-ofload (pol). in few years radio base stations became smaller and smaller, backbone access shrunk to box size and the data centers became the heart of the icT industry.

This higher level of digitalization impacted on the low power dc/dc conversion market though contributed to the development of higher power density bricks, up to the 1Kw mythic quarter brick.

POWER SUPPlIES

Figure 2 Powerbox GB350 digitally controlled power supply for demanding applications operated under high electromagnetic field (Source: iStock.com/baranozdemir – Powerbox) Increase of discrete solution considered by many as nessie, the loch ness Monster, the transition from low power dc/dc power modules to discrete solution is a reality and, with the miniaturization of telecom equipment and higher level of integration a building practice that is now well established.

quently published about the growing volume of pwM, it is not simple to quantify the transition volume from conventional board mounted dc/dc converters in the telecommunication segment though; a rough number of 65% of the low/mid power conversion function is now achieved by discrete solution, compared to only 15% 10 years ago.

This transition has been facilitated by the semiconductors manufacturers that developed-design support to a very advanced point, simplifying the implementation of low and mid power at board level and the development of highly integrated pol. despite number of market studies are fre-

combining lower market demand for conventional telecom equipment, higher integration and transition to discrete solution, the low and mid power dc/dc converters collapsed but at top level been compensated by the increase of higher power and other growing segments such as medical.

GROWING AREAS fUll Of INNOVATIONS Brut power it is obvious that radio base stations are getting smaller and, despite the expected number of 5g transmitters required by that new technology, the volume of low and medium power board mounted devices will never recover where they used to be during the peak days. That illustrates the impact of technology shift and challenges for power supplies manufacturers to always be ready for the next wave of innovations. with the booming of internet, data traffic amazingly increased, requiring data centers to process more and more, faster and faster, data than ever. More data/faster means more processors and more power supplies.

Because of the extremely high level of integration, certain boards will soon require more than 3Kw per board, which is not only a challenge to power but as well, how to keep such boards cooled enough. powering, with energy efficient solutions servers and other ip mass traffic routers requires from power designers to innovate in advanced topologies, use of new components such as gallium nitride or inventing efficient solutions to convert from the 400Vdc distribution voltage to 1Vdc required by the microprocessor.

POWER DESIGN

within the data center power community, the new motto is 400 to 1 @ 99, understanding 400Vdc input, 1Vdc output at 99% conversion ratio. for sure a bit challenging but as we say within the power community: “limits are made to be broken” and for the power pioneers, which i belong, we all remember the number of times we have been challenged to brake unbreakable limits!

1 and 0 are making the game There is another area where technology innovation contributed to boost power, efficiency and flexibility, which is the so called “digital power.” considered as anecdotic when presented first, the digital power technology originally developed for icT and high density data centers made its way through the others industries becoming the preferred platform by power designers when addressing new challenges. from a simple monitoring function to very advanced switching control, the number of power supplies using that technology grown exponentially and is even used in very advanced medical equipment such as Magnetic resonance imaging (Mri) where digital power combined with coreless technology make efficient power conversion possible in extreme condition (e.g. high magnetic field of 4 Tesla - figure 2). highly debated for almost a decade, the integration of a digital chain within power supplies opened a new range of applications, only few years ago, we couldn’t even though they will exist. from the internet of Things (whatever it falls under that category) to unmanned ships crossing ocean, the future power supplies will not be as it is today and power engineers already working on intelligent

power architectures able to self-control the way they operate. how far could that go? hard to say but with projects to bring men to Mars, unmanned vehicles, industry 4.0 and all other applications requiring extremely high reliability and full remote monitoring and control, it shouldn’t be too far and 2020 might be a good target.

POWER TO MEDICAl AND HOME HEAlTHCARE from 1.2 billion usd in 2016, the global market for medical power supplies is expected to expand at a cagr of 4.5% from 2017 to 2022. This growth results from a global population that is both living longer and experiencing an increasing rate of chronic disease, combined with economic factors that are driving the increased of healthcare in the home.

Beside conventional equipment for hospital and medicalized infrastructures, there is a growing demand for medical electrical equipment designed for use in home environment, requiring from power supplies manufacturers to not only consider standards and regulations but as well patient comfort and patient environment, for example by designing products for home environment such as the lenticular shape, eliminating hard shapes and avoiding wheelchair blocking.

Because of the nature of the medical segment and risk of electrical shock or malfunctioning equipment resulting from a faulty power source, power supply has to comply with stringent regulatory and certification systems. The implementation of the so-called iec 60601 4th edition is one example of safety regulation enforced in that industry but beside any regulation, power supplies manufacturers are taking own initiatives to develop processes integrating risk assessment far above what is required by the iso 14971 and to push manufacturing facilities to comply with the iso 13485. designing a power supply for medical requires not only the best power technology but a very high level of knowledge in regulations and field of applications. for power designers, internal or external medical power supplies are full of challenges and designing a product, which has high efficiency, high isolation, ultra-low leakage current and able to guarantee critical systems to work flawlessly is not an easy task.

That what makes this segment very interesting, especially when home healthcare increasing the interaction between the

patient and installed equipment, and considering many other aspects such as radio coexistence. for power supplies designers, the medical segment is probably one of the most demanding in terms of combined knowledge. Be a good power electronic designer is not enough anymore and it’s a real team work combining many disciplines that must work together, which makes the job very interesting with full of rich learning.

In conclusion: it is difficult to cover all areas compositing the 22-25 Billion envelop and it is for sure that a lot of things are also happening in other segments such as industrial implementing industry 4.0, lighting growing exponentially and some considering to integrate built-in power on silicon inside the led, the Transportation to integrate communication to power supplies for monitoring and preventing maintenance but it is easy to understand that, despite an overall number that seems to have been stable for more than five years, a lot of changes happened in the business composition. i would like to conclude this article buy a quote from Kenneth hildebrand: “Strong lives are motivated by dynamic purposes” which reflects very well, what we all, power supplies aficionados are aiming for. we like to brake unbreakable limits and the power industry is full of amazing challenges, which make it so exiting.

ACTIVE Components

AUTOMATING AMPLIFIER CIRCUIT DESIGN The semi-expert techniques for automating amplifier circuit designs calls for a combination of hard specification requirements and judgement margins. a design tool must support these techniques to zero in on the appropriate operational amplifier (op amp) and external components. figure 1 shows two fundamental circuit examples that implore this type of tool. yes, these are simple topologies – but the difficulty is in the detail when selecting amplifiers and external components to meet the performance criteria for the application.

By Bonnie C. Baker weBench® senior applications engineer REQUIREMENTS: MAPPING fROM MANY TO ONE The ultimate task is to find the perfect op amp for an amplifier circuit. in the case of selecting amplifiers from Texas instruments, this challenge requires the designer to sort through approximately 1300+ op amps.

These amplifiers come with many variations on their electrical perfor¬mance and specifications. The key specifications include power-supply ranges, bandwidth, input/output swing limits, and others. on top of these hard constraints, most amplifier choices use a series of overlapping issues, such as accuracy, noise, power, temperature drift, and/or ic cost. starting from ground zero, the first task is to sort amplifiers according to basic suitability

for the final design. as step one, the designer identifies the basic-circuit operational values. These values can be entered using a web-based amplifier design tool, such as the weBench® amplifier designer (figure 2).

appropriate op amp for the amplifier circuit. as a start, the provided power supply voltages can eliminate devices with supply voltages that are out-of-range. for example, the input values in figure 2 may be for a

• power supply voltages • circuit input and output signals • output load conditions • small-signal output bandwidth These design requirements allow the amplifier designer software to select an

dual-supply, ±5 V. from this infor¬mation, the software eliminates op amps with maximum power-supply ranges below 10 V, and minimum power-supply ranges greater than 10 V. additionally, the amplifier selection process removes amplifiers with excessively-high power-supply ranges. as for the amplifier’s input stage, the design tool ensures there is no violation to the op amp’s common-mode range. with

the output stage, the software makes sure that signals remain within the rail limits of the power supply, while taking a further step to ensure that the output swing is within the candidate-amplifier’s linear region. To achieve this, the software uses the amplifier’s output load conditions.

The tool offers four data entry styles for input voltages, output voltages, and gain. it also accommodates individual designer preferences as shown in figure 3.

These data inputs were used for the discussion on the following pages: Vcc = 12 V Vee = 0 V VinMin = 5.5 V VinMax = 6.5 V VouTMin = 0.5 V VouTMax = 11.5 V iouT source/sink current = 1 ma small signal bandwidth = 500 khz

during the transition from the view in figure 2 to figure 4, the software determines the resistor values in the target op amp circuit. it is easy to assign a generic feedback resistor (r2) value of 1 kΩ. however, a better general guide is to assign the values according to Table 1.

Gain bandwidth Gain bandwidth ≤ 0.01 MHz 0.01 MHz < Gain bandwidth ≤ 0.1 MHz 0.1 MHz < Gain bandwidth ≤ 10 MHz 10 MHz < Gain bandwidth ≤100 MHz 100 MHz < Gain bandwidth ≤ 1 GHz 1 GHz < Gain bandwidth ≤ 10 GHz

The algorithms that produce the amplifier designer Visualizer screen shown in figure 4 create a reduced list of op amps. The order of the amplifiers listed depends on which optimizer parameters have been selected. on the top left of figure 4 is a list of input design criteria and to the right is the optimizer box.

The optimizer box has three pull-down menus with the following options to set design priorities: • precision • noise • Temp drift • supply current • cost Figure 3: Voltage input and voltage output styles.

The question to ask is, of these five characteristics in the optimizer pull-down menus, which is the Very important, important, and less important? when the choice is completed, the solution Table in figures 4 shows updated results. additionally, further criteria refinements are possible with the menu in the upper right corner of figure 4. The choices available in this area are: • package group • number of channels • shutdown pin

Figure 4: Amplifier Designer Visualizer screen. for the last data entry, the design tool uses the small-signal bandwidth to identify suitable amplifiers. in an effort to take the amplifier’s process variations into account, the applied guard band for this specification is approximately 20 percent. www.international.electronica-azi.ro

SCREENING OP AMPS TO TARGET: VISUAlIzER SCREEN The next design screen was obtained by clicking the create amplifier design button.

The selections in this section are selfexplanatory, however, these selections further reduce the list of amplifiers. when the optimizer menu options are changed such that precision is selected as Very important, Temp drift as important, and supply current as less important, the opa140 should appear near the top of the list in the solution Table.

DESIGNER SUMMARY SCREEN The next step is to proceed on to the amplifier design summary screen. for the following discussion, the open design button was selected for the opa140 in the solution Table of the Visualizer screen. at this point, the amplifier has been selected and the circuit fully defined. The amplifier designer summary screen (figure 5) allows exploring the theoretical feasibility of the design. The center bar in figure 5 shows selection tabs for viewing calculated performance analysis, calculated performance Values, and the Bill of Materials. The calculated performance analysis segment produces input/output graphs as shown in figure 5.

There are menu selections to view ac, sine and square-wave graphical responses.

These curves are not a result of a simulation; rather the page shows calculated theoretical graphs. The intent is to provide a quick look at the circuit’s behavior before proceeding any further. The calculated performance Values tab allows viewing circuit characteristics in seven categories: 1. design criteria 2. operating frequency values 3. power requirements 4. Vos/ib error 5. VouT gain versus resistor tolerance 6. error over temperature 7. Total output noise within these seven categories, there are calculated performance values. for instance, the operating frequency values (#2 above) provides the amplifier bandwidth, amplifier

slew rate, closed-loop bandwidth, and fullpower bandwidth (fpBw).

AMPlIfIER DESIGNER SIMUlATION To proceed to the Ti spice simulation screen, click on the sim button at the top of the screen (not shown in figure 5).

The amplifier designer ports the complete circuit to the simulation screen. The amplifier simulation environment (figure 6) uses Texas instruments pspice® models while providing six simulation options: 1. sine wave 2. step response 3. closed loop response 4. dc sweep 5. Total noise 6. group delay with all of these simulation options, the amplifier designer provides the appropriate signal sources. There are options to modify the magnitudes, frequency, and timing of these sources. if this simulation environment is not suitable, it is possi¬ble to download the circuit into a Tina-Ti™ environment. weBench® amplifier designer offers this export option by clicking on the sim export button at the top of the simulation screen (not shown in figure 6).

Through this reference design, which is now in volume production, smartphone manufacturers are able to benefit from dramatic enhancements in image quality without any impact on the slim designs that consumers now expect from their handsets.

The new partnership combines seMco’s universally recognized expertise in camera module design and manufacturing, with corephotonics’ innovative camera-related technologies. it enables a far greater number of smartphone manufacturers to access ground-breaking imaging technology that will help them to elevate user experience.

The dual camera concept made possible by corephotonics’ proprietary technology presents smartphone manufacturers with the means to distinguish their handsets from those of their rivals through greatly improved imaging capabilities - with better zoom, increased effective resolution and broader dynamic range all being derived. it comprises one camera producing a wide field of view (foV) image - much like the technology found in a conventional smartphone. in addition, however, there is a second camera that features a telephoto lens - which addresses the narrow foV image. The result is an imaging mechanism that can deliver up to 3x optical zoom and provides the user with highly detailed photo26

MaXiMâ&#x20AC;&#x2122;s defiBrillaTion and esd proTecTion deVice safeguards Medical applicaTions wiTh 100X less leaKage currenT Targeting medical equipment such as defibrillators as well as ecg diagnostics and monitoring systems, the MaX30034 defibrillation protection device from Maxim integrated products, inc. protects against defibrillation pulses and electrostatic discharge (esd). compared to existing approaches and components, it simplifies design, provides >75% space savings, and trims the bill of materials, all while significantly improving performance. designers of defibrillators and ecg monitors face a challenge, as their ecg input amplifiers must withstand high-voltage pulses for cardiac resuscitation. These pulses can easily damage the sensitive electronic circuitry which captures the millivolt level heart signals. preventing this damage has required a three-layer, multicomponent approach combining a per-channel gas-discharge tube (gdT) and/or transient-voltage suppression (TVs) device, as well as esd-protection diodes. further, leakage current (a critical parameter) is relatively high, at about 1-2na.

Maxim's four-channel MaX30034 defibrillation protection device uses an innovative topology from an advanced semiconductor process to absorb and harmlessly redirect these highenergy pulses away from sensitive circuitry. This small and robust device needs only two external pairs of resistors for each channel to provide design simplicity, smaller overall size, and lower leakage current. The MaX30034 replaces the primary-level gdTs

and/or TVss, as well as secondary-level esd diodes which are the conventional solutions for mandated circuit protection. The device can withstand over 100,000 defibrillation pulses without failure and still maintain a leakage current under 10pa (100x less than gdT/TVs-based approaches).

renesas deliVers neXT-generaTion eMulaTor ThaT conTriBuTes To reduced eMBedded sofTware deVelopMenT TiMe renesas electronics announced the e2 emulator, a new-generation on-chip debugging emulator. The e2 is intended as a development environment for the latest devices in the renesas rh850, rX, and rl78 families of microcontrollers (Mcus), and for a selection of automotive system(s)-on-chip (socs). The new emulator supports the extended debugging functionality of the rh850 family and contributes to shortening the time required for can communication debugging and the current consumption debugging. recently, use of electronics for automotive control is increasing to improve the fuel efficiency, safety, and comfort of vehicles, and the number and variety of built-in sensors is growing. This leads to an increased size of control programs of Mcus used in electronic control units (ecus). since each ecu performs communication control via automotive networks such as can, lin, and flexray®, and dozens of ecus are installed in a single vehicle, communication control has become more complicated. additionally, considering that many ecus are installed in a vehicle, it has become more important to precisely understand current consumption when each ecu operates and optimize the control programs to achieve low current consumption in automotive systems. one challenge with existing ecu software development is that it is necessary to download the program from the emulator to the Mcu. and each time debugging code needs to be added to the www.international.electronica-azi.ro

control program, it increases the program size and download time. in the case of can communication, a significant contributor to this repetitive debug cycle is the need to use a can analyzer along with the emulator – these devices have not traditionally operated synchronously. in the case of low power optimization, the emulator is typically used side-by-side with an ammeter or current probe, and it is difficult to link the current consumption peak specifically to the matching point of time in the running code.

NEWS Vicor corporaTion inTroduces new cool-power ZVs BucK-BoosT regulaTor Vicor corporation announced a new addition to its growing pi37xx family of cool-power ZVs Buck-Boost regulators. delivering up to 140 watts of power, and up to 8 amps of output current, at up to 96% efficiency, the new pi3740 cool-power regulator features an input operating voltage range of 8 – 60Vdc and a regulated output voltage range of 10 – 50Vdc. incorporating Vicor’s proprietary high frequency zero-voltage switching (ZVs) technology, and featuring a best-in-class combination of conversion efficiency, power density and performance, the pi3740 is an ideal choice for demanding, automotive, industrial, test automation, led lighting, and battery charging. like all members of the pi37xx family, the pi3740 meets its performance specifications “out of the box” across the full breadth of its operating voltage ranges without the need for special circuit customizations. wide operating voltage ranges can enable a reduction in both the number of regulators and the number of power supply designs that must be designed, configured, manufactured, inventoried and maintained. The pi3740 converter, for example, can be used in a range of applications that would otherwise require the use of several different alternative regulators having narrower operating voltage ranges. for example, a power supply incorporating a pi3740 can be designed to operate from, or charge, both a 12V and a 24V battery source. and all Vicor pi37xx Buck-Boost converters feature seamless transitioning between Buck mode (input voltage is

greater than output voltage) and Boost mode (input voltage is less than output voltage) making them the best choice for applications in which the regulator input voltage varies above and below the output voltage. The pi3740 fully integrates its controller, power switches and support circuitry within a high density, thermally adept, 10mm × 14mm × 2.5mm sip (system-in-package).

inTersil announces single-chip rad hard 32-channel driVer wiTh inTegraTed decoder for saTelliTe applicaTions intersil corporation introduced a radiation hardened 32-channel driver with integrated decoder that reduces the size, weight and power (swap) of satellite command and telemetry systems. The isl72813seh is the industry’s first high current driver to integrate the decoder, level shifter and driver array in a single monolithic ic, allowing satellite manufacturers to significantly increase system capacity and reduce solution size by up to 50%. The device offers a 4x higher density channel count compared to the nearest competitor, and the integrated level shifter eliminates several peripheral components.

The isl72813seh driver leverages intersil’s proprietary silicon on insulator process, which provides single-event latch-up (sel) robustness in heavy ion environments. The driver’s integrated decoder interfaces directly to the general purpose i/os of fpgas and cpus in the satellite’s flight computer, dramatically reducing pin count compared to competitive 1-input to 1-output driver arrays. each of the device’s 32-channels of common-emitter open-collector driver outputs can generate pulses of up to 42V and 600ma. The isl72813seh addresses latching relay and solenoid commanding for most satellite control functions, including redundancy management, mechanism drive enables, propulsion component relays and enables, battery management, and payload switch control. The isl72813seh’s low Vce saturation levels

eliminate a major customer concern by reducing the overhead voltage required to drive the load. The driver’s power efficiency and high integration reduces the amount of circuitry required on the bus, allowing customers to add more spacecraft functionality and processing power.
