ELECTRONIC CIRCUIT AND LIGHT-RECEIVING CIRCUIT

摘要

PROBLEM TO BE SOLVED: To provide an electronic circuit and a light-receiving circuit which compensate for an offset of an input/output signal and are capable of performing an amplifying operation even when an input current increases.

SOLUTION: An electronic circuit 30 of the present invention comprises: a differential transimpedance amplifier 10 which converts a complementary input current into a complementary voltage signal and outputs it; and a differential circuit 18 which receives the output and whose output is connected to an input of the differential transimpedance amplifier 10 and whose current source Is5 is controlled on the basis of an average value I2 of the input current.
