ABSTRACT:
A horizontal charge coupled device (HCCD) is provided with a multiple reset gate in order to establish a more stable, less noisy voltage in an output node floating diffusion. Charges are transferred from an input of the HCCD to the floating diffusion by multiple, overlapping gate structures. Signal charges are detected or read out from the floating diffusion through an amplifier/inverter circuit. Periodically, the voltage of the floating diffusion is established to a reference level by application of a reset signal to a multiple reset gate structure, which results in charges in the floating diffusion being transferred to a reset drain. Noise induced by the reset operation is lessened on average due to the multiple reset gate structure.
