Classification: CPC H | IPC H

Claim 9:
10. A DC-DC converter, comprising:
a switching buck regulator including a driver and configured to output a first output signal, the driver configured to drive a first power switch and a second power switch;
a circuit connected to the switching buck regulator and including an adder, the circuit configured to generate a second output signal by performing a first operation on the first output signal, and output the first output signal and the second output signal using the adder; and
a controller connected to the adder, the controller including a first voltage controlled oscillator configured to receive the first output signal and the second output signal from the adder, a second voltage controlled oscillator configured to receive a reference voltage, a voltage controlled delay line, and a phase detector, the phase detector connected to the voltage controlled delay line that is connected to the first voltage controlled oscillator through a first path and connected to the second voltage controlled oscillator through a second path separate from the first path,
wherein the controller is configured to convert the first output signal and the second output signal into a time domain, perform a second operation on the converted first output signal and the converted second output signal, and perform a third operation to compensate for on a signal on which the second operation has been performed.
