Abstract
The invention relates to controlling a device for converting charge into voltage comprising an amplifier and at least one capacitor mounted in inverse feedback between an input and an output of said amplifier, whereby said amplifier can be connected between at least one input stage, to receive a charge therefrom, and at least one output stage to deliver voltage thereto, said voltage being representative of the charge received at the input, said method comprising at least one phase comprising the voltage conversion of a charge received at the input. According to the invention the conversion phase comprises at least: one first sub-phase during which the amplifier is connected to the input stage and the amplifier is disconnected from the output stage; followed, by a second sub-phase during which the amplifier is disconnected from the input stage and the amplifier is connected to the output stage.
