Abstract
The design of a CMOS analog VLSI synapse circuit that learns according to supervised or unsupervised learning rules is introduced. The sign of the weight change is determined by using a weight-change sensor circuit, and then a definite weight-change value is added to the old weight using a weight-updating circuit. The resulting system provides a small weight change, positive and negative weight values, and a simple controlling weight-change mechanism. Simulation results based on the Analog Workbench software are described
