Abstract
A first receiving terminal and a second receiving terminal are connected to a first signal transmission line and a second signal transmission line, respectively, and receive the input of transmission signals. A first resistor and a second resistor convert current signals contained in the transmission signals into voltage. A comparator inputs the respective voltages converted by the first and the second resistor, and outputs, as an output signal, a voltage corresponding to a difference between their voltages. A first transistor connected to an end of the first resistor and a second transistor connected to an end of the second resistor reduce the variation in a transmission voltage signal due to the variation in the current signals contained in the transmission signals. A third transistor connected to the other end of the first resistor causes to drop power-supply voltage so as to generate a control signal. The control signal is turned into a gate voltage of the second transistor in a crosswise manner. A fourth transistor connected to the other end of the second resistor operates in the similar manner to the third transistor.
