A regulating circuit for a high voltage generator, used in particular for supplying a non-volatile memory, includes an amplitude modulator (101) which receives at input terminals at least two clock signals (phi; nphi) and which supplies at output terminals at least two modulated clock signals (102; 103) to a charge pump (104). The circuit also includes a feedback loop, connecting an output of the charge pump to said amplitude modulator. This loop includes a comparator (109), which receives at a first input terminal an output quantity (Ibr) from the charge pump and at a second input terminal a reference quantity (Ipol), and which supplies at an output a comparison signal (Ucomp). The feedback loop further includes an analogue low-pass filter (105) at the output of said comparator converting said comparison signal into an analogue control signal (106) for the amplitude modulator.
