Abstract
A mixed-mode VLSI implementation of artificial neural networks offers a tradeoff solution for speed, area saving, and flexibility. In the Letter, a novel CMOS sampled-data programmable synapse and a simple CMOS analogue neuron have been developed. Using a 1.2-mu-m CMOS technology, the synapse consumed 120 x 120-mu-m2 and the neuron consumed 120 x 260-mu-m2.
