ABSTRACT:
A temperature-compensating bias circuit for biasing a transistor circuit such as a multivibrator is disclosed. In the bias circuit, a series circuit formed of a first resistor and a parallel circuit consisting of a first circuit includes a second resistor and n diodes and a second circuit which includes a third resistor and m diodes, is connected between a power source line and a ground line. A voltage generated from a bias output terminal for driving the multivibrator has the effect of cancelling temperature drift of the multivibrator, and includes temperature drift represented by a temperature coefficient which varies according to the number of diodes in the first and second circuits.
