Abstract :
A dual-channel horizontal-CCD (H-CCD) register scheme is essential to realizing high-density image sensors. However, fixed pattern noise will appear, unless precise care is taken in designing a transfer region connecting two H-CCD registers. This paper indicates that the fixed pattern noise is caused by an incomplete signal charge transfer between two H-CCD registers, due to the potential dip and barrier formed in the transfer region. A new transfer-region structure is proposed. It has been confirmed that the fixed pattern noise can be eliminated by this new structure
