Abstract
A power gating circuit is provided. The power gating circuit includes a logic gate group. The power gating circuit also includes a first switching circuit coupled to first and second supply voltages and the logic gate group. The power gating circuit further includes a second switching circuit coupled to the first and second supply voltages and the logic gate group. The first and second supply voltages are supplied to the logic gate group through the first switching circuit based on a voltage select signal. The first and second supply voltages are supplied to the logic gate group through the second switching circuit based on the voltage select signal and a power down signal.
