AN EFFICIENT CHARGE RECOVERY LOGIC-CIRCUIT

Efficient charge recovery logic (ECRL) is proposed as a candidate for low-energy adiabatic logic circuit. 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 th e same throughput as a conventional static CMOS CLA. Proposed logic sh ows four to six times power reduction with a practical loading and ope ration frequency range. An inductor-based supply clock generation circ uit is proposed. Circuits are designed using 1.0-mu m CMOS technology with a reduced threshold voltage of 0.2 V.
