摘要:
A drive circuit includes: an input-side inverter circuit and an output-side inverter circuit connected to each other in series and inserted between a high voltage line and a low voltage line. The output-side inverter circuit includes a CMOS transistor having a first gate and a second gate, in which a drain is connected to the high voltage line side and a source is connected to an output side of the output-side inverter circuit. The output-side inverter circuit further includes a MOS transistor in which a drain is connected to the low voltage line side and a source is connected to the output side of the output-side inverter circuit. The output-side inverter circuit further includes a correction circuit correcting a voltage of one or both of the two gates of the CMOS transistor.
