Efficient charge recovery logic

Abstract

Efficient Charge Recovery Logic (ECRL) is proposed as a candidate for low-energy adiabatic logic. Power comparison with other logic circuits is performed on an inverter chain and a carry lookahead adder (CLA). ECRL CLA is designed as a pipelined structure for obtaining the same throughput as a conventional static CMOS CLA. Proposed logic shows 4-6 times power range with a practical loading and operation frequency range. Circuits are designed using 1.0 /spl mu/m CMOS technology with a reduced threshold voltage of 0.2 V.
