ABSTRACT:
The present invention relates to the charge pump circuit and, more particularly to the charge pump circuit which can decrease the time period of voltage rise of the charge pump circuit by making the charge pumping voltage outputted from the output stage of the pump circuit section to be satisfactorily supplied to the load section, by making the rate of the gate voltage rise of the voltage drop transistor to be higher than the rate of drain voltage rise.
