Abstract
A receiving circuit in accordance with an exemplary aspect of the present invention includes a first voltage-dividing circuit that outputs a first input signal obtained by voltage division of one of differential signals based on the resistance ratio between first and second resistors, a second voltage-dividing circuit that outputs a second input signal obtained by voltage division of the other of the differential signals based on the resistance ratio between third and fourth resistors, a differential amplifier that amplifies the differential component between the first and second input signals, a common-mode voltage detection circuit that detects the common-mode voltage of the differential signals, and a bias voltage switching circuit that switches the voltage value of a bias voltage based on the common-mode voltage.
