Power gating is one of the power reduction techniques that is mostly suitable for low power VLSI applications. It reduces the power consumption by shutting of the current to the blocks not in use. Hybrid power gating is applied to Modified Adiabatic Logic based Full Adder (ALFA) cell. The proposed ALFA cell reduces the energy consumption by 67.21%, 51.31%, 55.86% and 27.01% when compared to CMOS FA, PTL with TG 16T, hybrid CMOS and PTL with TG 14T. ALFA cell with hybrid power gating technique reduces the power consumption by 1.76, 2.08%, 1.13%, 1.44%, 0.48% and delay by 5.92%, 11.19%, 11.19%, 5.92%, 24.92% when compared to ALFA cell with NMOS sleepy approach, PMOS sleepy approach, PMOS sleepy stack approach, NMOS sleepy stack approach and dual stack approach.
