Low leakage power gating technique for subnanometer CMOS circuits

Abstract

Static power has become the most important factor in the fabrication of integrated circuits. Power gating techniques minimize leakage currents and help to develop ultra-low power and high-performance digital circuits. In this paper, a power gating approach is proposed to minimize leakage for subnanometer technologies. Simulation results reveal that the proposed technique reduces maximum of 96% leakage power, 33% dynamic power, 49% drowsy power, and 16% energy as compared to conventional techniques. The proposed technique offers good leakage reduction, even under variation of different operating parameters.
