Performance Comparison of CNFET-Based (8:2) and (8:3) Compressors

Abstract

Compressors are known as a key processing elements to accumulate and reduce partial products in a parallel manner in multipliers. This paper conducts a comprehensive analysis and comparison between two highorder (8:2) and (8:3) compressors based on Carbon Nanotube Field Effect Transistor (CNFET) technology. Furthermore, two well-known Full-Adder (FA) are also employed within the cells to analyse and compared for speed, power consumption, and power-delay product at transistorlevel. Simulations are carried out using Synopsys HSPICE with 32nm CNTFET technology.The results of simulation demonstrate the superiority of the (8:3) compressor in terms of power and Power-Delay Product (PDP) around 67% and 44% respectively in comparison with (8:2) compressors by deploying symmetrical CNT Full-Adder cells. \uf020
