Abstract
An array of photodetector is organized along a first organizational axis on a semiconductor substrate of a first conductivity type. Each photodetector is at least partially formed in the substrate which forms a first electrode of the photodetector. A peripheral polarization ring is formed around the array of photodetectors. The polarization ring is connected to a polarization voltage generator and to the substrate. A read circuit is connected to a photodetector via the second terminal of the photodetector. A first switch connects the photodetector to a generator of an additional voltage. A second switch connects the photodetector to the associated read circuit. The first and the second switches are in opposite states.
