Abstract

A voltage boosting circuit includes a plurality of unit circuits provided in parallel, and a control unit. Each of the plurality of unit circuits includes a charge capacitor connected to an anode of a rectifying element at one end and to a discharge control signal at the other end, and a charge transfer section transferring a charge from the charge capacitor to the charge capacitor of a next one of the plurality of unit circuits in response to a transfer control signal. The last one of the plurality of unit circuits further includes a last rectifying element, and a last capacitor connected to an anode of the last rectifying element at one end and to a discharge control signal at the other end. The charge transfer section in the last unit circuit transfers a charge from the charge capacitor to the last charge capacitor in response to the transfer control signal. Cathodes of a plurality of the rectifying elements and a cathode of the last rectifying element are connected together with each other. The control unit supplies a plurality of the discharge control signal and a plurality of the transfer control signals to the plurality of unit circuits.
