Voltage generation circuit of charge pump type, with a self-oscillating control circuit

摘要

The present invention relates to a potential generation circuit of charge pump type, this circuit including at least two stages formed of capacitors and of circuitry for isolating or interconnecting the capacitors, to generate an output potential by charge transfer between the stages. The circuit is driven by two control potentials oscillating between a first and a second value. The circuit includes a self-oscillating control circuit to generate control potentials, to eliminate time delays between charge and discharge phases.
