Abstract
A device is disclosed that includes a circuit block coupled to a local power node, and a power gating circuit coupled between the local power node and a global power supply. In one embodiment, the power gating circuit includes a first plurality of first switching devices with a first threshold voltage, and a second plurality of second switching devices with a second threshold voltage that is different from the first voltage threshold. The power gating circuit may isolate the local power node from the global power supply based on an isolation signal.
