A generator circuit is connected to a second terminal of the ramp capacitor and adapted to generate a voltage ramp at the terminals of the ramp capacitor. The generator circuit includes a constant current source SCC connected to the second terminal B12 of the ramp capacitor CAP1 and auxiliary circuit MAX adapted in the presence of a transient variation of the power supply voltage to determine the transient current flowing in the ramp capacitor and generated by the transient variation. Responsive thereto, delivery is made to the second terminal B12 of the ramp capacitor CAP1 of a charging current equal to the algebraic sum of the constant current delivered by the constant current source and an auxiliary current equal and opposite to the transient current.
