ABSTRACT:
A first circuit which is constituted by a thin film resistor is connected between the collector of a transistor and a power supply terminal, and a second circuit which is constituted by a semiconductor resistor is connected between the emitter of the transistor and a grounding terminal. The film thickness of a thin film resistor is set to not more than its skin depth at a frequency to be compensated for.
