Abstract:
An image sensor includes a horizontal shift register electrically connected to a pixel array for receiving charge packets from the pixel array. A non-destructive sense node is connected to an output of the horizontal shift register. A charge directing switch is electrically connected to the non-destructive sense node. The charge directing switch includes two outputs. A charge multiplying horizontal shift register is electrically connected to one output of the charge directing switch. A discharging element is connected to the other output of the charge directing switch.
