Performance analysis and simulation of two different architectures of (6:3) and (7:3) compressors based on carbon Nano-Tube Field Effect Transistors

In this paper, two different architectures of (6-3) and (7-3) compressors, including the conventional topology based on full adder cells with the most interesting of those recently proposed and XOR/MUX based topology, are analyzed and compared for speed, power consumption and power-delay product at transistor-level in Carbon Nano-tube Field Effect Transistor (CNFET) technology. Simulations are carried out using Synopsys HSPICE with 32nm CNTFET technology. The results of simulation demonstrate the superiority of the XOR/MUX-based structures in terms of PDP and propagation delay around 9% and 14% respectively.
