Abstract
A pulse-width modulation signal generator having a pre-phase converter which includes N pre-delay circuits connected in cascade, and N main phase converters each of which includes M main delay circuits, where N and M are natural numbers greater than one, and N>M. The output of each of the N pre-phase circuits is supplied to one of the N main phase converters to generate phase converted clock signals used for generating a pulse-width modulation signal.
