Patent ID: 7176709

Claim:
A receiving device for data transfer with a differential-current driven model, comprising: a first receiving node connected to a first transmission line and a second receiving node connected to a second transmission line for receiving a differential current signal; a first current-voltage conversion device to convert current into a voltage corresponding to a first current signal from the first receiving node; a first impedance matching device to match input impedance to characteristic impedance of the first transmission line, installed between the first receiving node and the first current-voltage conversion device, including a first low impedance circuit device that enables generation of a low impedance which is lower than the characteristic impedance of the first transmission line that is connected to the first receiving node as an input impedance of the first receiving node; a second impedance matching device to match input impedance to characteristic impedance of the second transmission line, installed between a second receiving node and a second current-voltage conversion device, including a second low impedance circuit device that enables generation of a low impedance which is lower than the characteristic impedance of the second transmission line that is connected to the second receiving node as an input impedance of the second receiving node; and a comparator into which a differential-voltage signal from the first and the second current-voltage conversion devices input as a comparison signal, and outputs a comparison result thereof as an output data.
