Low‐power high‐performance CMOS 5‐2 compressor with 58 transistors

Abstract

Compressors are the fundamental components in the partial product reduction stage of CMOS multipliers. A new design is presented for the CMOS 5-2 compressor with 58 transistors, which is the lowest reported device count for such a circuit. Simulation results show that the proposed 5-2 compressor has significantly improved power–delay performance compared to previously proposed approaches.
