This paper presents design of adiabatic sequential circuits using power-gating techniques. Adiabatic flip-flops with data-retention function are described, which are realized with CPAL (complementary pass-transistor adiabatic logic) circuits. The power-gating scheme using DTGAL (dual transmission gate adiabatic logic) circuits is proposed for adiabatic sequential circuits. The design of power-gating adiabatic sequential circuits is explored. A practical sequential system realized with the proposed power-gating scheme is demonstrated using a mode-10times5times5 counter. Simulations show that energy loss of the adiabatic sequential circuits can be greatly reduced by using the power-gating scheme.
