Abstract:
A complementary pulse width modulation circuit is composed of a signal generating circuit 10 for generating first and second pulse width modulation signals (PWM#1 and PWM#2) 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 circuit 20 for combining a positive signal and a negative signal of the first pulse width modulation signal (PWM#1) generated by the signal generating circuit, and for combining the first pulse width modulation signal (PWM#1) combined with the second pulse width modulation signal (PWM#2), followed by outputting.
