An integrated circuit is provided. The integrated circuit includes a power gating circuit configured to receive a power supply voltage from a first power line and to output a first driving voltage to a first virtual power line and a logic circuit electrically connected to the first virtual power line and configured to receive power from the power gating circuit. The power gating circuit includes a first p-type transistor and a first n-type transistor connected in parallel between the first power line and the first virtual power line.
