CCD structures for signal and image analog processing

摘要

The set of CCD structures for analog realization of main arithmetic operations such as a summing up, a subtraction, and a multiplication is presented. Using these structures it is possible to create various circuits and arrays for signal and image analog processing. Several types of these circuits and arrays are described. An analog filters with constant and random weights and Sobel's transformation circuit have been created. Some experimental results are given.
