Abstract:
1. A reference voltage generating circuit comprising: a first switching element of a first conductivity type having a first end connected to a first terminal, and a second end short-circuited to a control end thereof; a second switching element of a normally-on type and of a second conductivity type having a first end, a second end connected to the second end of the first switching element, and a control end to which a bias voltage is applied; a third switching element of the normally-on type and of the second conductivity type having a first end short-circuited to a control end thereof and connected to a reference voltage output terminal, and a second end connected to the first end of the second switching element; a bias voltage generating section configured to generate the bias voltage that is lower than the reference voltage from the reference voltage; and a fourth switching element of a normally-off type and of the second conductivity type having a first end connected to a second terminal, a second end to which the bias voltage is applied, and a control end connected to the control end of the third switching element.
