Design and comparison of different 4:2 compressors based on 180nm technology

Abstract

Many of the circuits such as portable devices, digital signal processing filters, compressors are basic building block for high performance. Different logic types of 4:2 compressors are designed and their performance is computed. The new design uses, different logic style which cut down power consumption and delay. For getting high speed and consuming less power, the new compressor are proposed which consists of eight transistors (8T) XOR-XNOR unit. Different models get designed and simulated using Cadence Virtuoso tool (180nm). From simulation results we reached the improvement of less power consumption, speed of proposed 4:2 compressors.
