Energy Recovery Circuit Design for Low Power VLSI

VLSI design arena finds real time applications operating on the principle of adiabatic logic, which realizes significantly lower power dissipation levels than conventional static CMOS circuits. Research on adiabatic logic has resurged with increasing impetus on secure cryptographic hardware systems. This tutorial delves into the adiabatic logic circuits found in literature, namely, ECRL, 2N-2N2P, PFAL, DCPAL and PSAL, highlighting their operational features, energy recovery characteristics, energy and loss models. The advantages of using adiabatic logic in secured hardware systems are highlighted through a brief glimpse into the recent literature.
