The invention relates to charge-pump circuits used for the generation, in an integrated circuit, of an internal supply voltage Vpp which is considerably greater than the external supply voltage Vcc. In a charge pump configuration with capacitors and transistors, certain transistors must be driven by...http://www.google.fr/patents/US5589793?utm_source=gb-gplus-shareBrevet US5589793 - Voltage booster circuit of the charge-pump type with bootstrapped oscillator
