Abstract
A complementary pulse width modulation circuit is composed of a signal generating circuitfor generating first and second pulse width modulation signals (PWM#and PWM#) that are complementary to each other from an input signal (IN) in response to a sampling synchronous signal (Sample) generated in synchronization with a clock (CLK); and a signal output circuitfor combining a positive signal and a negative signal of the first pulse width modulation signal (PWM#) generated by the signal generating circuit, and for combining the first pulse width modulation signal (PWM#) combined with the second pulse width modulation signal (PWM#), followed by outputting.
