Abstract:
A light-emitting unit outputs an optical signal corresponding to an input electric signal. A light-receiving unit is electrically insulated from the light-emitting unit and outputs an electric signal according to the received optical signal as an output signal. In the light-receiving unit, a first light-receiving device outputs an optical current according to the optical signal. A second light-receiving device is provided not to receive the optical signal. A current duplication circuit duplicates a current flowing through the second light-receiving device. A current-voltage conversion circuit converts a current, which is generated by subtracting the current duplicated by the current duplication circuit from a current flowing through the first light-receiving device, into a voltage signal. A comparator output a result of a comparison between the voltage signal converted by the current-voltage conversion circuit and a threshold voltage as the output signal.

Claim (Index 1):
A light receiving circuit, comprising:\n a first photo diode to which an optical signal is input; a second photo diode; a light shielding member configured to shield the second photo diode from the optical signal; a first differential amplifier, a first voltage being input to one input of the first differential amplifier; a first resistor, one end of the first resistor being connected to an output of the first differential amplifier; a first transistor, one end of the first transistor being connected to one end of the first photo diode; a second transistor constituting a current mirror with the first transistor, one end of the second transistor being connected to one end of the second photo diode, the other input of the first differential amplifier, and the other end of the first resistor; and a comparator, one input of the comparator being connected to the output of the differential amplifier, a second voltage being input to the other input of the comparator.
