Abstract
The phase margin compensation method according to an exemplary embodiment of the present invention includes: outputting reference voltage (Vout); outputting a first reference voltage (Vout) actually supplied to the target circuit; comparing the reference voltage (Vout) with the first reference voltage (Vout) by the comparator; counting any section of an output signal (pulse signal) from the comparator by a predetermined frequency by the duty cycle calculator; and controlling a phase margin of a frequency of output voltage supplied to the target circuit by controlling buffer current based on the duty cycle ratios and the output bit information fed back from the duty cycle calculator.
