Patent ID: 8479374

Claim:
A method for producing an image capture device comprising: providing a horizontal shift register electrically connected to a pixel array for receiving charge packets from the pixel array; providing a non-destructive sense node connected to an output of the horizontal shift register; providing a charge directing switch electrically connected to the non-destructive sense node, the charge directing switch being configured to receive charge from the non-destructive sense node and supply the received charge either to a first output or a second outputs; providing a charge multiplying horizontal shift register electrically connected to the first output of the charge directing switch; providing a first amplifier electrically connected to an output of the charge multiplying horizontal shift register, the first amplifier being configured to receive charge from the charge multiplying horizontal shift register and output a voltage signal corresponding to an amount of the charge received from the charge multiplying horizontal shift register; and providing a second amplifier, different from the first amplifier, electrically connected to the second output of the charge directing switch, the second amplifier being configured to receive charge from the charge directing switch and output a voltage signal corresponding to an amount of the charge received from the charge directing switch.
