Due to the increasing demand of portable equipments and their capability, including computational power and reliability, reducing power consumption has become an important aspect in the field of integrated circuits design. Adiabatic logic (or so called energy recovery logic) is a design style to reduce power consumption. The rule of adiabatic switching can circumvent the CV2 barrier of dissipated energy which is generated by operating CMOS circuits in a conventional way. The energy dissipated in adiabatic circuits can be distinguished into two kinds: adiabatic loss and non-adiabatic loss. An adiabatic circuit can't avoid adiabatic loss. But adiabatic logics usually can only reduce part of non-adiabatic loss. This thesis explains the reason of existence of adiabatic loss, and proposes four kinds of new adiabatic logics which use bootstrapping and charge recycling techniques. Simulation results of an 8-bit carry look-ahead adder show that the Energy Recovery Complementary Pass-transistor Logic we proposed can saves 84.4% power dissipation compared to conventional CMOS dissipation.
