Abstract
A first input receiving a voltage to be sampled formed by a terminal of a sampling capacitor. An amplifier has a first input connected to another terminal of the sampling capacitor and a second input connected to a reference voltage. The amplifier is supplied by a power supply configured to deliver a reduced current and to supply the amplifier in a first condition during a first period, deliver a rated current and to supply the amplifier in a second condition during a second period, the reduced current being lower than the rated current. During the first period, the first and second inputs of the amplifier are short-circuited.
