Low-power Complementary Pass-transistor Adiabatic Logic and Sequential Circuits

We present a complementary pass-transistor adiabatic logic(CPAL) for low-power design,which is driven by two-phase AC power supply.The bootstrapped nMOS switch is employed to eliminate non-adiabatic loss on output loads.Its energy dissipation is in less dependency on power-clock frequency.The adiabatic D,T and JK flip-flops are proposed.A synthesis method for adiabatic synchronous sequential circuits is proposed.A practical sequential system based on the proposed adiabatic D flip-flop is verified.SPICE simulations demonstrate that the designed circuits have correct logic function and considerable power saving.
