ABSTRACT:
A first periodic pulse is rectified to generate an internal voltage by a charge pump circuit. A level detector is provided for detecting whether or not the internal voltage reaches a desired level. The charge pump circuit is controlled by a controller in accordance with the detection signal so that the internal voltage may take the desired level. A switch element switched by a second periodic pulse is provided in the current path of the level detector. A leakage current path for allowing a lower electric current than the electric current to flow through the former current path is provided between the output terminal of the charge pump circuit and a predetermined power supply terminal.
