ABSTRACT:
In a reference voltage generating circuit, a standardized constant voltage measured on the basis of a low power supply voltage as a reference is generated by a constant voltage source connected between a high power supply voltage and the low power supply voltage. The standardized constant voltage is divided by a series circuit composed of first and second resistors sandwiching first and second transistors therebetween, for generating a divided voltage, which is then supplied to a current source composed of a third transistor. A current flowing through the current source is converted into an output voltage measured on the basis of the high power supply voltage as a reference, by third and fourth resistors series-connected to sandwich the third transistor therebetween. The output voltage is converted, by an emitter follower composed of a fourth transistor having a base receiving the output voltage, into a reference voltage measured on the basis of the high power supply voltage as a reference.
