Abstract
Disclosed is a high voltage generator circuit of the charge pump type. The rate of operation of this pump is set by a sequence of piloting signals produced out of a clock signal. This clock signal is itself produced by an oscillator. A frequency servo-link is set up between the clock signal produced by the oscillator and the running of the sequence in order to produce a clock signal with a frequency that is equal to the maximum permissible frequency for low supply voltages while at the same time limiting this frequency from a given supply voltage threshold onwards.
