Abstract
A high dynamic range charge collection circuit is described which includes additional electrodes between the photogate and the transfer gate electrode to create charge transfer wells of different depths. The charge-coupled device has a nonlinear relationship between the charge transferred out of the sensing region and the charge generated in the photosite.
