ABSTRACT:
A circuit includes a plurality of stages each including a MOS transistor and a capacitor of which one end is connected to one of a drain and a source of the MOS transistor. The plurality of stages are connected with each other by cascade connection of the MOS transistors. A gate of the MOS transistor is connected electrically to one of the drain and the source thereof in each stage, and a substrate for at least one pair of adjacent MOS transistors are connected electrically to one of the drain and the source of one of the pair. The back bias effect is suppressed, and the layout area is reduced. Further, a plurality of booster capacitors connected in series are provided in succeeding stages, thereby suppressing degradation of breakdown voltage of each capacitor.
