A charge transfer device (CTD) eliminating the background level of a detected signal provided with an input circuit comprising an injection source (12) and an electrode (16) controlling a storage potential well, which can be subdivided into an evacuation well (18) and an output well (19) separated by the separation potential produced by a separation electrode (27). This CTD is characterized in that its input circuit comprises a floating electrode (25) connected to the separation electrode (27) in order that the separation potential controls the background level and an insulation electrode (28) insulating the reference well (29) from the output well (19), during the measuring operations, the respective dopings under the floating electrode and under the separation electrode being obtained in order that the potential wells situated under each of these respective electrodes have different depths.
