Abstract
A pulse width modulation signal with a less distortion component that is not influenced by a common-mode noise or an offset voltage is generated. Pulse signal generation circuitsgenerate pulse signals S, Swhose pulse widths are discharge times t, tof integrators, respectively, a PWM signal generation circuitdetects discharge end timings of the integratorsbased on the pulse signals S, S, and a pulse whose pulse width is a time between discharge end timing of one of the integratorsand discharge end timing of the other one of the integratorsis generated so as to be output as a PWM signal S.
