A charge pump, to generate a voltage (overvoltage) greater than the supply voltage, includes disk capacitors triggered via an oscillator circuit, the first terminals of the disk capacitors being connected to the oscillator circuit and their second terminals being wired together in a node to which the overvoltage is applied. The oscillator circuit includes an R-C phase shifter oscillator at whose outputs three output signals, phase shifted 120 DEG , are applied, and the outputs are connected to disk capacitors via differential voltage current amplifiers.
