Trade-off between dynamic range and sampling rate in a charge coupled device is virtually eliminated in the serpentine charge coupled device of the present invention. In this device, for each charge packet transferred in a first direction, a plurality of n charge packets are transferred in a second transverse direction in the serpentine register. Accordingly, for a given charge transfer rate in the first direction, the charge coupled device clock frequency is increased by a factor of n. The serpentine register is formed on the semiconductive substrate having two parallel channel stops extending in a first direction and a plurality of parallel interlaced channel stop fingers extending in a second direction which are alternately connected to the two parallel channel stops. Charge transfer is accomplished under the control of a plurality of n parallel electrodes extending in a first direction formed in a first level above the substrate and a second plurality of parallel electrodes formed in a second level above the substrate which extend diagonally in a third direction. A complementary pair of clock signals are alternately connected among the first electrodes and among the diagonal electrodes. |
