ABSTRACT:
The weighted product of two digital signals obtained with a digital weighted template with corresponding binary signal stored within a two-dimensional matrix. Data is loaded into a circuit in word serial and random access modes. The weighted signal product is obtained using a vertical charge injection technique with sensing of the substrate analog charge flow. The substrate charge collection output permits a true summation of processed analog signals to provide the desired weighted product.
