A bias voltage supply circuit having a relatively stable constant voltage during load current fluctuations and driven by a relatively low DC power supply voltage, which includes a DC power supply terminal, a DC current source, a first transistor connected at its collector to the DC power supply terminal via the DC current source, a first resistor connected between the emitter of the first transistor and a reference potential terminal, a second transistor having its collector-emitter circuit connected in parallel with the series circuit of the DC current source and the first transistor, the base of the second transistor connected to the collector of the first transistor, a second resistor connected in parallel with the collector-base circuit of the first transistor and an output terminal connected to the base of the first transistor. |
