Charge-coupled signal processing devices are attractive for applications in such systems as communication, radar and sonar because of the ability of a single rather simple device to perform the equivalent of a large number of arithmetic operations per second. For example, a 32-point transversal filter(1) operating at 20 MHz is performing 1.2 x 109 operations per second which is the equivalent of a fair size digital processor. However, conventional CCDs have not gained wide spread acceptance in commercial or military systems because of the lack of availibility of CCDs with sufficient cost, power, weight and throughput advantages over competing digital techniques to make them attractive for integration into otherwise digital hardware.
