Abstract:
A power-gate circuit includes a power-gate transistor operable to switch to decouple a first supply voltage from a second supply voltage during an idle mode, and to couple the first supply voltage to the second supply voltage during a full operational mode. Part of the charge stored at a gate terminal of the power-gate transistor, would have been otherwise flushed to ground while turning on the power-gate transistor, is routed to the rail of the second supply voltage of the logic block. Part of the charge on the rail of the second supply voltage is used to charge the gate terminal of the power-gate transistor to deactivate the power-gate transistor if the logic block goes to the idle mode. Energy is saved both ways because of the charge recycling and the ability to use the power-gate circuit even in cases where the duration of the idle mode may be short.

Claim (Index 1):
A circuit comprising:\n a first supply node to receive a first supply voltage; a second supply node to receive a second supply voltage; a power-gate transistor having a control terminal, a first terminal coupled to the first supply node, and a second terminal coupled to the second supply node, wherein the power-gate transistor is to switch between a first state in which the power-gate transistor is off to decouple the first supply node from the second supply node and a second state in which the power-gate transistor is on to couple the first supply node with the second supply node; a switch coupled between the control terminal of the power-gate transistor and the second supply node; and control circuitry to control the power-gate transistor and the switch, the control circuitry to temporarily close and then open the switch as part of a first transition of the power-gate transistor from the second state to the first state and as part of a second transition of the power-gate transistor from the first state to the second state.
