摘要

A mechanism is provided for an integrated circuit with power gating. A power header switch is configured to connect and disconnect any circuits to a common voltage source. A powered off circuit is disconnected from the common voltage source. A first capacitor and a second capacitor are configured to supply wakeup electrical charge to a given circuit of the circuits. The first capacitor and the second capacitor are connectable to the given circuit and the powered off circuit. A controller is configured to controllably connect the first capacitor and/or the second capacitor to the given circuit in order to supply the wakeup electrical charge to the given circuit, when the powered off circuit was previously connected to the first capacitor and/or the second capacitor.
