  • Optical sensor
    Patent number: 11478634
    Abstract: An optical sensor, especially an artificial retina, that includes at least one photosensitive cell. Each cell includes a integration capacitor, a read circuit the operation of which depends on the charge of the integration capacitor, at least one MOS transistor operating subthreshold, and the drain-source current of which influences the charge on the integration capacitor, and at least one photodiode operating in photovoltaic mode and connected to the gate of this transistor, such that the drain-source current of the MOS transistor depends on the optical power received by the photodiode.
    Type: Grant
    Filed: October 24, 2018
    Date of Patent: October 25, 2022
    Assignees: ÉCOLE CENTRALE DE LILLE, UNIVERSITÉ POLYTECHNIQUE HAUTS-DE-FRANCE, CENTRE NATIONAL DE LA RECHERCHE SCIENTIFIQUE, YNCREA HAUTS DE FRANCE, UNIVERSITE DE LILLE
