Performance Analysis of CMOS and FinFET based 16-Bit Barrel Shifter

Abstract

A barrel shifter shifts ‘n’ number of bits in one cycle. Barrel shifter can perform the following functions: shift left logical, shift left arithmetic, rotate left, shift right logical, shift right arithmetic and rotate right. The design of the barrel shifter is purely MUX based will improve its efficiency if Mux consumes less power. The MUX based SLC barrel shifter circuits are designed using Tanner EDA tools. Fin-type field-effect transistors ( FinFETs) are promising substitutes for bulk CMOS in nano - scale circuits. This paper compares the performance of barrel shifter using two different technologies on the basis of power consumption, time delay and power delay product
