Abstract

A power gating circuit includes a first current switch, a second current switch, and a switching controller. The first current switch is connected between a power rail and a circuit block operated by an operating supply voltage, and provides a first current when turned on. The second current switch is connected between the power rail and circuit block, and provides a second current larger than the first current when turned on. The switching controller turns on first current switch when transitioned from a sleep mode to an active mode to change the operating supply voltage using the first current, generates a reference voltage based on the operating supply voltage that changes more slowly than the operating supply voltage, and turns on the second current switch based on the reference voltage to provide the second current to the circuit block.
