Abstract

See full text

An integrated circuit includes an amplifier for amplifying an electric current signal from an external light receiving element, and a low-pass filter. The low-pass filter has a resistor and a capacitor serial-connection in which multiple capacitive elements are serially connected. With respect to the resistor in the low-pass filter, one end thereof is connected to a power terminal to which the bias voltage is inputted, and the other end thereof is connected to an input terminal of the capacitor serial-connection and to a bias application electrode of the light receiving element through which the bias voltage is applied. With respect to the capacitor serial-connection in the low-pass filter, each connection terminal between two of the serially connected capacitive elements and an output terminal of the capacitor serial-connection, are connected to their respective capacitance terminals to which a ground potential as a reference for the bias voltage is connected selectively.
