ABSTRACT:
A linear image sensor array and process having a two stage transfer circuit where in order to reduce non-uniformities between the photosite cells of the array resulting from difference transistor thresholds, the bias charge is injected between the first and second transistors of the two stage transfer circuit, with the first transistor function as a metering gate for bias charge injection.
