Calculation of charge-handling capacity in twin-layer peristaltic charge-coupled devices

Charge-handling capacity is an important parameter in determining the dynamic range of a charge-coupled device (CCD). Based on depletion approximation, a one-dimensional charge storage capacity calculation is given for an n-channel twin-layer peristaltic CCD with constant layer dopings. The charge capacity is found to increase linearly with surface layer implant dose for lower level implant and saturate at higher level implant.
