Original Abstract Submitted
A charge pump circuit includes: first and second capacitors; a first switch element group turned on and off by a first clock signal and connecting a first voltage supply line and the first capacitor when turned on; a second switch element group turned on and off by the first clock signal and connecting a second voltage supply line and the second capacitor when turned on; and a third switch element group turned on and off by a second clock signal and connecting a voltage output line and the first and second capacitors when turned on. A control circuit controls a timing of a signal change of a first enable signal so that the signal levels of the first and second clock signals are fixed when the first and second switch element groups change from off to on, in response to stopping oscillating the first and second clock signals.
