ABSTRACT:
A pseudo differential circuit is a circuit system taking the advantages of both a CMOS circuit and a differential circuit. However, when process variability and the like are taken into account, a cross point of positive and negative outputs is not constant, thereby increasing a variation in duty of an output waveform. A semiconductor circuit according to the present invention includes: a first transistor being of a first conductivity type, coupled between a first power supply and an output terminal, and applied with an input signal; a second transistor being of a second conductivity type and coupled between a second power supply and the output terminal; a third transistor being of the second conductivity type and coupled between the first power supply and the output terminal; and a fourth transistor being of the first conductivity type and coupled between the second power supply and the output terminal.
