Abstract

Operational Transresistance Amplifier (OTRA) is a Current Controlled Voltage Source (CCVS) characterized by low impedance, thereby producing circuits insensitive to stray capacitances. This paper presents an OTRA implementation of a multimode semi Gaussian (S-G) shaper that supports voltage and transimpedance modes of operation. A comparative study of performance indicators like Signal to Noise Ratio (SNR) and Total Harmonic Distortion (THD) is included. The results obtained from SPICE simulations using 0.5 μm CMOS technology model parameters depict a perfect Gaussian shaped output waveform that contributes towards decreasing Inter Symbol Interference (ISI) by overcoming irregularities during transmission of pulse in the channel.

Design and Implementation of Low Power ALU Using 8T Full Adder with FinFETs

Volume 5 Issue 4 September - November 2017 Research Paper Design and Implementation of Low Power ALU Using 8T Full Adder with FinFETs M. Chandra Sekhar Reddy*, P. Ramana Reddy** * Research Scholar, Department of Electronics and Communication Engineering, JNTUA, Anantapuramu, Andhra Pradesh, India. ** Professor, Department of Electronics and Communication Engineering, JNTUACEA, Anantapuramu, Andhra Pradesh, India. Reddy, M. C. S., and Reddy, P. R. (2017). Design and Implementation of Low Power ALU Using 8T Full Adder with FINFETS.  i-manager’s Journal on Circuits and Systems , 5(4), 8-14.  https://doi.org/10.26634/jcir.5.4.13939 Abstract An Arithmetic and Logic Unit (ALU) is an advanced circuit that performs number-crunching and rationale operations. ALU is an essential building piece of the focal preparing unit of a PC. The power, devoured by the ALU has a direct effect on the power disseminated from the processor. Thus, a plan is required to execute the ...

Power Efficient Functional Units For High Speed Computations.  i-manager’s Journal on Circuits and Systems , 1(3), 13-18.  https://doi.org/10.26634/jcir.1.3.2443 Abstract Power consumed per unit switching activity in a CMOS based computational unit is greatly dependent on the power consumption of the sum and carry generation units. This paper is focussed on reducing area and PDP of the computational units through gate level and transistor level optimisation. At transistor level 6T Mux based CMOS-CPL XOR gates with stable rise and fall times ar...
