Abstract
A PWM (Pulse Width Modulation) circuit of the present invention includes a reference pulse sequence generating section for outputting a reference pulse sequence, an up-down counter, a trigger signal generating section for generating from an input signal a trigger signal for the up-down counter having a period which is a natural number multiple of one cycle the period of PWM, and a comparator for comparing the output of the up-down counter and the reference pulse sequence.
