In this paper, the authors deal with comparative study of conventional CMOS circuits with CMOS based reversible logic circuits employing adiabatic switching methods. The power dissipation an important characteristics are tested by means of SPICE circuit simulation techniques for a CMOS AND-OR-Inverter (AOI) gate. Results from both conventional and adiabatic logic switching simulations are compared. The breakdown of adiabatic operation for these reversible circuits, due to the finite threshold voltages, is tested by checking the logic circuit node current/voltage transient waveform during the logic switching transitions.
