Abstract

A boosting circuit boosts a voltage of a load capacitor which is charged by a specific voltage. The boosting circuit comprises a boosting capacitor one end of which is connected to receive a clock signal, a charging circuit for charging the boosting capacitor, a gate circuit provided between the load capacitor and the other end of the boosting capacitor, and a gate control circuit for opening the gate circuit upon discharging of the charge of the boosting, that is controlled by the clock signal, to the load capacitor and for closing the gate circuit during discharging of the load capacitor. The charging circuit is provided separately from a circuit for supplying the specific voltage. The charges of the boosting capacitor under the control of the clock signal flow through the gate circuit to the load capacitor.
