Four flip-flop-like adiabatic logic circuits, suited for a standard cell library implementation, were compared in terms of absolute energy consumption and effectiveness of adiabatic energy recovery. The energy performance of ECRL, IECRL, PAL and PFAL logic circuits was determined, by means of SPICE simulation, as a function of capacitive load and operational frequency. The comparison showed that the PFAL circuit is the best flip-flop-based adiabatic solution as far as power consumption is concerned.

Abstract
Four flip-flop-like adiabatic logic circuits, suited for a standard cell library implementation, were compared in terms of absolute energy consumption and effectiveness of adiabatic energy recovery. The energy performance of ECRL, IECRL, PAL and PFAL logic circuits was determined, by means of SPICE simulation, as a function of capacitive load and operational frequency. The comparison showed that the PFAL circuit is the best flip-flop-based adiabatic solution as far as power consumption is concerned.File in questo prodotto:
