Abstract

An efficient implementation of a Hopfield-type, fully connected neural-network architecture is presented. It is based on a pulse-density-modulation technique implemented using switched-capacitor structures. The synaptic weights are programmable, and thus the area of one synapse and the entire network depends on the resolution of the weight. Advantages of the design are simple synapse structure and thus small area, expandability, and modularity.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
