ABSTRACT:
A reference voltage generating circuit comprising a first and second transistors whose base-to-emitter voltages are different from each other and a constant current source to drive said respective transistors. Since the base-to-emitter voltages are different from each other, the circuit scarcely has a temperature characteristic with a reduced circuit scale. The first and second transistors preferably have different emitter areas. The current source is preferably a current mirror circuit composed of third and fourth transistors whose emitter areas are different from each other to drive the first and second transistors by different currents.
