A New High-Performance Bridge Structure for 4- to-2 Compressor using CMOS and CNFET Technology

Abstract

Abstract-In this paper, a new high-speed and energy efficient 4-to-2 compressor cell was presented using carbon nanotube field effect transistors (CNFETs). CNFET is very suitable for high-frequency and lowvoltage applications. In addition, in this paper several conventional and state-of-the-art 4-to-2 compressor cells are surveyed and compared. In order to evaluate the proposed designs, computer simulations are carried out using 32nm-CMOS and 32nm-CNFET technologies. Simulations are conducted using various low voltage power supplies, different temperatures, frequencies and load capacitors. Results of simulation demonstrate predominance of the proposed design in terms of power consumption, delay, and power-delay product (PDP) compared to other 4-to-2 compressor cells and they confirm that the proposed design is the fastest 4-to-2 compressor in various working circumstances.
