ABSTRACT:
A powergating circuit includes a P-channel transistor with a source coupled to VCC, a gate for receiving a first boosted or non-boosted powergating control signal, and a drain forming the internal switched VCC power supply. An N-channel transistor has a source coupled to VSS, a gate for receiving a second boosted or non-boosted powergating control signal, and a drain forming the internal switched VSS power supply. The powergating circuit further includes a circuit for forcing the first and second internal power supply voltages to a mid-point reference voltage during the standby mode.
