Abstract
The present invention is directed to a charge coupled device in which, during the shifting interval, the charge storage pixels are biased with an electrical potential greater than the absolute value of the CCD inversion potential and, during the charge integration interval, the charge storage pixels are biased with an electrical potential that is less than the CCD inversion potential. In this manner, the present invention substantially reduces error attributable to impact ionization or dark current.
