SUMMARY This paper presents a low‐power sinusoidal supply circuit for our proposed adiabatic logic (2PC2AL). The proposed supply circuit consists of three parts: LC resonant circuit, voltage generator circuit, and peak control circuit. The proposed circuit is simulated using 0.18 μm CMOS technology. The simulation results show that the power dissipation of the proposed voltage generator is 10.8 μW at a 100 nA load, and that of the proposed sinusoidal supply circuit is 35.5 μW at 100 kHz. The power dissipation values of the adiabatic/nonadiabatic 16‐bit MPU decoders are also compared. At transition frequencies of 10 kHz to 1 MHz, the proposed decoder with a sinusoidal supply circuit shows a maximum reduction of 75% in power dissipation from to that of a static CMOS.
