Low leakage power switch

Abstract:

Computer systems may include multiple power switch circuits for coupling circuit blocks to power supply signals. Different power supply signals may be selected for use in the generation a control signal for a power switch device in the power switch circuit. For example, during a particular operating mode of a power switch circuit coupled to a circuit block, a power supply signal with a voltage level greater than an power supply signal for the circuit block may be used to generate the control signal.
