ABSTRACT:
A reference voltage generation circuit includes a first current conversion circuit for converting a forward voltage of a p-n junction into a first current proportional to the forward voltage, a second current conversion circuit for converting a voltage difference between forward voltages of p-n junctions differing in current density into a second current proportional to the voltage difference, a current add circuit for adding the first current from the first current conversion circuit to the second current from the second current conversion circuit, and a current-to-voltage conversion circuit for converting a third current into a voltage. MIS transistors are used as active elements other than the p-n junctions. This enables the less temperature-dependent, less power-supply-voltage-dependent output voltage of the reference voltage generation circuit to be set at a given value in the range of the power supply voltage, which enables semiconductor devices to operate on 1.25V or lower.
