Abstract

We present a dual transmission gate adiabatic logic (DTGAL) for low-power design, which is driven by three-phase AC power supply. First, the energy recovery principle in CMOS circuits is analyzed. Then, the adiabatic D, T and JK flip-flops are proposed. A practical sequential system designed with the adiabatic D flip-flop is demonstrated. SPICE simulations demonstrate that the designed circuits have correct logic function and considerable power saving.
