METHOD AND DEVICE FOR READING ELECTRICAL CHARGES PRODUCED BY A PHOTO-DETECTOR, AND DETECTOR COMPRISING SUCH DEVICES

摘要

A method of reading electrical charges produced by a photo-detector of a photo-detector matrix includes collecting and storing electrical charges produced by the photo-detector in a first capacitive element, transferring the charges stored in the first capacitive element to a second capacitive element, and reading the voltage at the terminals of the second capacitive element. The transfer followed by the reading is carried out in at least two phases: at least one first phase taking place during the collection and storage of the charges in the first capacitive element, and a second phase taking place at the end of the collection and storage of the electrical charges in the first capacitive element.
