ABSTRACT:
Provided is an electronic device including a charge pump circuit whose circuit structure is simple and boosting efficiency is high. The charge pump circuit uses MOSFETs as charge transfer elements and has a structure in which a voltage of a gate of a charge transfer MOSFET is controlled to a predetermined level based on a dividing voltage caused by a first resistor connected between a source and the gate thereof and a second resistor connected between a drain and the gate thereof and a clock pulse for on/off control of the charge transfer MOSFET is supplied to the gate through a capacitor.
