This chapter is concerned with adiabatic logic circuits. First, it introduces adiabatic charging which forms the basis of adiabatic circuits. The difference between adiabatic charging and conventional charging of a capacitor is highlighted. As amplification is a fundamental operation performed by electronic circuits to increase the current or voltage drive, adiabatic amplification is considered. The steps of realization of adiabatic logic gates starting with its static complementary metal–oxide–semiconductor (CMOS) counterpart are explained. The realization of pulsed power supply, which is the most fundamental building block of adiabatic circuits, is introduced. The realizations of both synchronous and asynchronous pulsed power supplies are explained. How stepwise charging and discharging can be used to minimize power dissipation is explained. Various partially adiabatic circuits such as efficient charge recovery logic (ECRL), positive feedback adiabatic logic (PFAL) and 2N-2N2P are introduced. Non-adiabatic loss in adiabatic circuits highlighted. The impact of voltage scaling and threshold voltage scaling on the partially adiabatic circuits is discussed.
