A pulse modulated signal (ei) output from a pulse modulator ( 1 ) and a feedback signal (ef) containing distortion caused by a power switch ( 3 ) are integrated in a first integrator ( 21 ) and a second integrator ( 24 ), respectively, and are input to input terminals of a comparator ( 25 or 29 ), respectively, so that a correction signal (Vc) is generated.
