Abstract

In this paper, the design of pre-settable adiabatic flip-flops and sequential circuits based on the two-phase CPAL (complementary pass-transistor adiabatic logic) is presented. The two-phase CPAL is more suitable for the design of flip-flops and sequential circuits, as it uses fewer transistors than the conventional CMOS implementation and the other adiabatic logic circuits. Pre-settable adiabatic flip-flops (D and T) based on the two-phase CPAL are proposed. Adiabatic flip-flops with a reset line are more universal and suitable for the design of sequential circuits. A practical sequential system realized with the proposed pre-adiabatic flip-flops is demonstrated. SPICE simulations show that the energy loss of the proposed pre-settable adiabatic flip-flop and sequential circuits is greatly reduced compared to the conventional CMOS implementation
