FDTD-based Time Domain Analysis of CMOS Gate Driven Interconnects M. Kavicharan*, N.S.Murthy, N. Bheema Rao Department of ECE, National Institute of Technology, Warangal, India Abstract Accurate time domain analysis of CMOS gate driven interconnects is important for the design and analysis of high performance VLSI systems. Conventionally, CMOS driver is approximated as a constant resistance instead of non-linear and time-varying MOS resistance, which causes inaccurate modeling of CMOS driver. This paper presents a new method for FDTD-based transient analysis of CMOS gate driven interconnect line using a generalized model. The generalized model of CMOS inverter includes non-linear effects such as carrierâ&#x20AC;&#x2122;s velocity saturation effect of short channel devices, while distributed interconnect RLC model is analyzed using conventional FDTD with second order accuracy. The simulation results of the proposed method are in good agreement with LTspice results and considerable savings in CPU computation time is observed.

Keywords: CMOS driver, FDTD method, time domain analysis, distributed interconnects

Improvement of Design Issues in FinFET based Design Techniques for XOR and XNOR Circuits at 45 nm Technology Neha Yadav1, Ashish Kumar Singhal2* 1

Research Scholar of ITM University, India Department of EE, SR group of Institution, Jhansi (U.P), India

Abstract The scaling of conventional CMOS circuit inclines to the short channel effect due to leakage current increase in the circuit. To minimize the short channel effect, FINFET can be used in place of conventional CMOS circuits. This paper demonstrates comparative performance study of high speed, low power and low voltage on XOR and XNOR digital circuit. This paper assesses and compares the performance of XOR and XNOR logic circuits. This comparison is based on analysis of various design technique for XOR and XNOR logic circuits. The performances of XOR and XNOR circuits are based on CADANCE VIRTUOSO tool at voltage supply 0.6 voltages and the temperature is 260C and all the simulation results have been generated by Cadence SPECTRE simulator at 45 nm technology. The XOR and XNOR circuits with pass transistor, inverter based design, transmission gate and with feedback transistors designs are desirable for arithmetic circuits. Simulation results reveal low power, delay, power, delay product (PDP), average dynamic power consumption and energy delay product (EDP).

Automization In Diamond Industry H.S. Makda*, Ashish M. Kothari, Mangalia Avani, Trivedi Khyati, Nagda Gunjan Department of Electronics & Communication Engineering Atmiya Institute of Science & Technology, Rajkot, Gujarat, India

Abstract The rapidly increase in the technology in diamond industry makes it possible to cut, shape and polish diamond in the beautiful and artistic manner with less time consumption. But the process is very costly as extensive manpower is required in this technology. The various processes involved in this technology such as cutting into parts, polishing are done by the manpower. Above all the small things like to count the diamond problem is neglected. As the size of the diamond is too small the counting person needs a sharp eye to count with accuracy without any mistake. Thus this process is very much time consuming, as well it may cause eye problem in future to a counting person. Thus our goal of this project invention relates to the problem of counting of a diamond of too small size or to large size. Tools are used in this project are image processing for counting and micro-controller interfaced with displaying the counts of the diamond. The image of diamonds is captured and using matlab in image processing, after the image is processed and the counting of diamond is possible after that the data stored in matlab will given to micro-controller through the interfacing of matlab and micro-controller it will able to be display the number of diamonds counting on the LCD.

Keywords: Diamond counting, matlab programming, image processing

Three Stage High Step-up Interleaved Boost Converter with Voltage Multiplier Cell Arundathi Ravi* Department of EEE, Sathyabama University, Chennai, India

Abstract In this paper, three stage high step-up interleaved boost converter with three voltage multiplier cells (VMCS) and three state switching cells (3SSC) is proposed. Here an interleaved boost converter is used, as a result higher efficiency and reduced input ripple current is obtained. Also, an additional stage of voltage multiplier i.e., three stages is added so that voltage gain will increase. It reduces switching loss and stress through the devices. Moreover, by employing the three-state switching cell, the size of the inductor is reduced because the operating frequency of the inductor is double of the switching frequency. The current share between the active switches allows further reduction of the conduction losses in case of two stage circuit. The new method has been examined under various scenarios such as switching loss, ripples, stress and conduction loss. A detailed comparative study is done between two stage multiplier cell and three stage multiplier cell is made regarding power, efficiency, total stress and losses. The simulation of proposed converter with input voltage of 12 V and output of 115 V was done using MATLAB and the simulation result was validated. Finally, a prototype was built for an input voltage of 12 V, 70 V output voltage and 14 W output power.

Keywords: voltage multiplier cell, interleaved boost converter, high voltage gain, efficiency
