Descripción: Technology scaling increases the density and performance of nanometer circuits, resulting in both large dynamic and leakage dissipations. This paper presents power-gating scheme, modeling, and optimization of adiabatic flip-flops operating on near-threshold regions to reduce both dynamic and leakage dissipations. The power-gated logic blocks are realized with complementary pass-transistor adiabatic logic with the dual threshold technique to reduce active leakage dissipations. The improved complementary pass-transistor adiabatic logic circuits are used as the two-phase power-gating switches to reduce the sleep leakage dissipations. The analytical model for power-gating adiabatic sequential circuits was constructed, and the energy overhead of the proposed power-gating scheme was analyzed in detail. Near-threshold computing for a power-gating adiabatic mode-10 counter was verified. The results show that the proposed power-gating technique is suitable for the adiabatic units operating on near-threshold regions.
