Abstract
A light receiving circuit includes: a transimpedance amplifier circuit which is connected to a light receiving element; a differential amplifier which operates by a predetermined current supplied by a current source to output a current corresponding to a differential signal between a signal outputted from the transimpedance amplifier circuit and a predetermined reference signal; a current mirror unit which outputs a current corresponding to the current outputted from the differential amplifier; and a conversion unit which converts the current outputted from the current mirror unit into voltage.
