Abstract:
1. A light-receiving circuit comprising: a first MOSFET having a source, a drain, a gate and a back-gate; a first light-receiving element including a first terminal having a first polarity and a second terminal having a second polarity opposite to the first polarity, the first terminal of the first light-receiving element connected to the gate of the first MOSFET, so as to apply a first voltage, which is induced by a light signal incident on the first light-receiving element, to the gate of the first MOSFET, the second terminal of the first light-receiving element being directly connected to the source of the first MOSFET; and a second light-receiving element including a first terminal having the first polarity and a second terminal having the second polarity, the first terminal of the second light-receiving element connected to the back-gate of the first MOSFET, so as to apply a second voltage, which is induced by the light signal incident on the second light-receiving element, to the back-gate of the first MOSFET, the second terminal of the second light receiving element being directly connected to the source of the first MOSFET.
