Abstract
A charge-coupled device image sensor includes (a) a two-dimensional array of pixels having a plurality of rows and columns, the two-dimensional array includes: (i) a plurality of gates arranged as a charge-coupled device; wherein the array further includes a plurality of charge-coupled devices that are arranged to be clocked by one or more common timing signals; (ii) a transition region, electrically connected to the array, having a first and second row of gates in which the second row is electrically mated into a plurality of first and second pairs of gates in which first pairs of gates are clocked by a first common timing signal and second pairs of gates are clocked by a second common timing signal; wherein the first row of gates are all clocked with a third common timing signal; and (b) a horizontal shift register adjacent the second row of gates for receiving charge from the second row of gates.
