ABSTRACT:
A semiconductor device includes a differential signal output circuit that outputs a differential signal, an amplitude control signal generation circuit that generates an amplitude control signal to control an amplitude of the differential signal for the differential signal output circuit, and a center voltage level control signal generation circuit that generates a center voltage level control signal to control a center voltage level of the differential signal. The differential signal output circuit outputs the differential signal having the center voltage level based on the center voltage level control signal and an output level based on the amplitude control signal. A forming region of the center voltage level control signal generation circuit and a forming region of the differential signal output circuit are provided near each other on a semiconductor substrate where operation characteristics of transistors formed respectively in the two forming regions become equal.
