ABSTRACT:
A semiconductor device includes a three or more-stage semiconductor charge pump. The capacitance of a pumping capacitor that increases and decreases the potential of a final-stage node on the output side is larger than that of a pumping capacitor that increases and decreases the potential of another-stage node.
