Abstract
An exemplary embodiment matches the input impedance of the receiving device to characteristic impedance, even with the receiving device composed with the MOS transistor, with a receiving device for data transfer with the differential-current driven model including: a receiving node to receive a differential current signal; a current-voltage conversion device to convert current into a voltage corresponding to differential current signal from the receiving node; an impedance matching device to match the input impedance to characteristic impedance, including a low impedance circuit device that enables generation of a low impedance which is lower than the characteristic impedance of a sending-side transmission line that is connected to the receiving node as an input impedance of the receiving node; and a comparator into which a differential-voltage signal from the current-voltage conversion device is input as a comparison signal, and which outputs the comparison result thereof as an output data.
