ABSTRACT:
A multiplying circuit in which a pair of common-base transistors each having a small emitter area are inserted between the common emitter terminals of first and second differential amplifiers, which amplify a signal input to an input terminal pair and are connected in such a way as to cancel out their outputs which correspond to the input signal, and the output terminal pairs of multiple third differential amplifiers, which amplify a signal input to another input terminal pair and have a predetermined DC offset characteristic.
