Abstract
A semiconductor device includes a charge pump circuit having a plurality of booster units which are connected in series between an input terminal and an output terminal, each of the plurality of booster units includes: a main transistor that is diode-connected so as to cause a forward current to flow in a direction from an internal input terminal toward an internal output terminal; a sub-transistor that is connected between a first terminal of the main transistor and a back-gate terminal of the main transistor and has a control terminal connected to a second terminal of the main transistor; a resistor that connects the second terminal of the main transistor and the back-gate terminal of the main transistor; and a capacitor that is connected between the internal output terminal and a clock wire.
