Abstract
A receiver circuit, which is connected with a partner transmitter circuit through a signal line and receives a signal based on current which flows through the signal line, includes a current/voltage conversion circuit which converts the current which flows through the signal line into voltage, a power supply circuit which adjusts the current which flows through the signal line based on a bias voltage Vb and voltage of a node NDX connected with the signal line, and a bias voltage generation circuit which outputs the bias voltage Vb which is adjusted in connection with characteristics of the power supply circuit.
