  • Image sensors with noise reduction
    Patent number: 10757351
    Abstract: In various embodiments, image sensors and methods of operating the image sensors are disclosed. In an example embodiment, a pixel circuit having a first electrode is coupled to a reset transistor and to a first region of an optically sensitive layer, and a second electrode is coupled to a pixel sense node and to a second region of an optically sensitive layer. The electrical path from the first electrode, through the optically sensitive layer, and into the second electrode functions as a variable resistor. Other devices and methods of operating the devices are disclosed.
    Type: Grant
    Filed: September 23, 2018
    Date of Patent: August 25, 2020
    Assignee: INVISAGE INC.
    Inventors: Emanuele Mandelli, Ralph Beaudouin, Aurelien Philippe Bouvier, Dario Clocchiatti, Lionel Barrymore Joseph Barrow, Zachary Michael Beiley
