摘要： A multi-phase voltage regulator includes a pulse width modulation control unit, a pulse signal extension circuit, M counts of current providing paths, and a feedback signal switching circuit. The pulse width modulation control unit generates N counts of pulse signals in a first cycle period. The pulse signal extension circuit receives the N counts of pulse signals in a second cycle period and divides the N counts of pulse signals into M counts of pulse signals, wherein M=N×2K, K is a positive integer, and the second cycle period is 2K times the first cycle period. The M counts of current providing paths generate corresponding M counts of sensing voltages. The feedback signal switching circuit receives the M counts of sensing voltages, successively switches the M counts of sensing voltages into N counts of sensing voltages, and transmits the N counts of sensing voltages to the pulse width modulation control unit.
