Abstract: PURPOSE: A comparison device is provided to obtain a stable offset voltage even when the potential of a differential signal is varied. CONSTITUTION: In a comparison device(1) having offset, a master comparison circuit(2) supplies a comparison current(Icomp) according to a difference(Va) between differential signals of transmission lines(TX, XTX). A reference differential voltage generating circuit(4) generates differential voltages(OFS, XOFS) in accordance with the intermediate voltage(Vm) of the differential signals, and a servant comparison circuit(5) provides the current depending on the difference between the differential voltages as an offset current(Ioffset). The comparison device having offset outputs difference current between the comparison current and offset current so that it has an offset depending on input/output characteristics thereof. Since the master comparison circuit and servant comparison circuit have the same circuit configuration, the offset current varies with the change of characteristic of Va-Icomp of the main comparison circuit in accordance with the intermediate voltage. Accordingly, the offset voltage of the comparison device does not change even if the potentials of the differential signals are varied.
