ABSTRACT:
A differential amplifier produces a collector current of an output side transistor as an output current signal. In this case, a power supply voltage or a closer voltage to the power supply voltage is supplied to a collector terminal of the output side transistor. First and second current mirror circuits produce a current signal in response to the output current signal. The produced current signal passes through a resistor, a terminal of which is connected to a reference voltage. When the produced current signal passes through the resistor, a voltage drop from the reference voltage occurs at the resistor. By utilizing the voltage drop at the resistor, an output voltage changing in response to two output voltage signals is produced.
