A charge preamplifier device (100) integrated in a chip (200) of semiconductive material comprising: an input (IN) for an input signal (ii N) and an output (OUT) for an output signal ( VOUT); a substrate (202) of semiconductive material doped according to a first type of conductivity; an electrically insulating layer (204) placed on said substrate (202); a feedback capacitor (C f) integrated in the chip (200) and comprising a first electrode (3) connected to the input (IN) and a second electrode (2) connected to the output (OUT). The second electrode (2) is formed by a doped conductive region (205) having a second type of conductivity, opposite to the first type of conductivity, and integrated in the substrate (202) in order to face the first electrode (3).

6. Drawings
