Abstract
A method and apparatus for controlling a power switch are disclosed. A power switch may be coupled between a power supply signal and a virtual power supply signal coupled to a circuit block. The power switch may be configured to couple the power supply signal to the virtual power supply signal based on a first control signal, and reduce a voltage level of the virtual power supply signal to a voltage level less than a voltage level of the power supply signal based on a second control signal. The power switch may be further configured to change a current flowing from the power supply signal to the virtual power supply signal based on a third control signal.
