Abstract

This paper describes a novel switched-capacitor design for the implementation of artificial neural networks in VLSI using the pulse-stream signalling mechanism and dynamic weight storage. Test results are presented from a small number of chips, paying particular attention to the synaptic weight linearity and storage time. The synaptic weights are fully-programmable and the VLSI chips can be used to process analogue sensor data in real time with an accuracy equivalent to 6 or 7 bits, as demonstrated in the robotics application described in the paper.
