Classification: CPC G  H | IPC G  H

Claim 0:
1. A system on chip (SoC) for receiving an external supply voltage, the SoC comprising:
a first core configured to receive a first supply voltage through a first power rail and perform an operation in response to a first clock signal; and
a power manager configured to manage the first supply voltage,
wherein the power manager comprises:
a plurality of header switch circuits configured to connect, in response to a plurality of control signals, the first power rail to a second power rail through which the external supply voltage is supplied; and
a voltage regulator configured to compare the first supply voltage with a target voltage in a state in which supplying the first clock signal to the first core is suspended, and generate the plurality of control signals based on a comparison result,

wherein the voltage regulator is further configured to generate a compensation supply voltage for the first core based on a difference between the first supply voltage and the target voltage in the state in which supplying the first clock signal to the first core is suspended.
