増幅回路。 A pair of transistors are differentially connected, an input signal is applied to the base of one transistor, negative feedback is applied to the base of the other transistor from an output terminal via a resistor, and a predetermined current is caused to flow through the resistor. In the differential amplifier circuit, the voltage of the output terminal is maintained at a predetermined value by a constant current transistor whose collector is connected to the common emitter of the pair of transistors, and 12 collector currents of the collector current of the constant current transistor. and a compensation circuit whose output terminal is connected to the base of the other transistor in order to cause a current corresponding to the collector current of the compensation transistor to flow through the output terminal. Amplification circuit.
