1. A regulator system for regulating output current of a charge pump circuit, said output current having a magnitude being controlled by a set of clock signals coupled to said charge pump circuit, said regulator system comprising:

  • a control circuit which generates a set of at least one control signal as a function of said output current; and

    a clock circuit which generates said set of clock signals having a magnitude and a frequency, said magnitude depending on said set of at least one control signal;

    said set of clock signals being applied to said charge pump circuit thereby varying said magnitude of said output current.
