Abstract
A semiconductor integrated circuit device is provided which comprises a first charge pumping circuit comprising a plurality of MOS transistors cascade-connected between an input voltage node and a booster output node, where, of all associated nodes, those odd-numbered nodes receive one of first and second clock signals through a corresponding capacitor and those even-numbered nodes receive the other clock signal through a corresponding capacitor, a second charge pumping circuit comprising a plurality of MOS transistors cascade-connected between the input voltage node and the booster output node and equal in number to those of the first charge pumping circuit where, of all associated nodes, those odd-numbered nodes receive one of first and second clock signals through a corresponding capacitor and those even-numbered nodes receive the other clock signal through a corresponding capacitor and the gates of the respective MOS transistors are connected to the gate of the corresponding MOS transistors, and a high resistive element connected to an output terminal of said first charge pumping circuit.
