Method and device for reading electrical charges produced by a photo -detector and detector comprising such devices

摘要

The method involves collecting and storing electrical charges produced by a photo-detector in an integrating capacitor. The charges stored in the integrating capacitor are transferred to a read capacitor. The voltage at terminals of the read capacitor is read. The transferring of the charges is carried out in two phases in which one of the phases takes place during the collection and storage of the charges in the integrating capacitor and the other phase takes place at the end of the collection and storage of the electrical charges in the integrating capacitor. An independent claim is also included a device for reading electrical charges produced by a photo-detector of a photo-detector matrix.
