Abstract:
1. A charge coupled device comprising: (a) a plurality of non-adjacent, first gate electrodes; (b) a plurality of second gate electrodes with one second gate electrode placed between every other pair of first gate electrodes; (c) a plurality of third gate electrodes with one third gate electrode placed between remaining pairs of first gate electrodes not having a second gate electrode therebetween; and (d) a first timing signal connected to the plurality of first gate electrodes, a second timing signal connected to the plurality of second gate electrodes, and a third timing signal connected to the plurality of third gate electrodes, wherein, in a full resolution mode, the first gate electrodes are clocked substantially 180 degrees out of phase with respect to the second and third gate electrodes and the second and third gate electrodes are clocked substantially equally; and wherein, in a half resolution, double speed mode, the second and third gate electrodes are clocked substantially 180 degrees out of phase with respect to each other and substantially 50% duty cycle and the first gate electrodes are clocked with 25% or less duty cycle and 90 degrees out of phase with respect to the second gate electrodes.
