Abstract

PURPOSE:To reduce output distortion greatly by increasing the forward voltage drop of a diode by an MOSFET used for a PWM output circuit. CONSTITUTION:With regard to MISFETs Q1 and Q2, their substrates 7 and substrate electrodes 8 are in nonohmic contact at least at the output sides, e.g., in regions under the drains, so that the ON characteristics of a diode D1 between the source and drain of one N channel MOSFETQ2 are in conformity with ON resistance via the channel part of the other P channel MOSFETQ1. Therefore, a current flows through the channel part and forward and backward ON resistances are equal, reducing output distortion greatly.
