Abstract:
A light receiving circuit includes an inverting amplification circuit, a first light receiving element, a first circuit, and a charging circuit. The inverting amplification circuit includes an input terminal and an output terminal. The first light receiving element is connected between the input terminal and a reference potential terminal. The first circuit includes a first resistor, a second resistor, a third resistor and a capacitor. The first resistor second resistor connected through a connection point. The first resistor is connected between the input terminal and the connection point, and the second resistor connected between the output terminal and the connection point. The third resistor is connected between the connection point and connection node, and the capacitor is connected between the connection node and the reference potential terminal. The charging circuit connected between the power supply terminal and the connection node.
