ABSTRACT:
A signal processing circuit comprises a structure wherein emitters of a plurality of transistors are commonly connected, an inverting amplifier is connected to a base of each of the plurality of transistors, and an absolute value of an input signal supplied to the inverting amplifier is detected. The signal processing circuit has a compensating circuit to compensate a fluctuation of a voltage due to the plurality of transistors.
