Abstract:
A reference voltage generation circuit includes a first current-mirror circuit including a first MOS transistor connected to a first power source and a second MOS transistor of the first conductive type connected to the first power source; a second current-mirror circuit including a third MOS transistor and a fourth MOS transistor; a first resistor connected to the first node; a first bipolar transistor having a collector connected to the first resistor, an emitter connected to a second power source, and a base connected to the first node; a second bipolar transistor having a collector connected to the second node, an emitter connected to the second power source, and a base connected to the first bipolar transistor; a fifth MOS transistor connected between the first power source and an output terminal; and a third resistor connected between the output terminal and the second power source.
