  • Method of amplifying charge in an imager
    Patent number: 7910874
    Abstract: A charge coupled device (CCD) includes a low noise charge gain circuit that amplifies charge of a cell dependent upon the charge accumulated by the cell. The low noise charge gain circuit receives clocking signals, such as from an input diode, which allow charge to accumulate in a reservoir well and then flow into a receiving well. The low noise charge gain circuit also receives a voltage signal corresponding to charge accumulated on an associated cell. The amount of charge flowing into the receiving well depends on this voltage signal.
    Type: Grant

    Date of Patent: March 22, 2011
    Assignee: Imagerlabs, Inc.
    Inventors: Gene Atlas, Mark Wadsworth, Richard H. Kullman, Sarit Neter
