NEURAL NETWORKS

The first description of ANN integrated circuit implements a continuous time analog circuit for AM. The design used a 22 x 22 matrix with 20,000 transistors, averaging 40 transistors per node to implement a Hopfield AM network. The design faced a scalability challenge at higher levels of integration. The paper advocates handling larger problems by a collection of smaller networks or hierarchical solutions, while predicting, “Significantly different connection technologies ” as essential for success in larger systems
