Abstract :
This paper examines analog CMOS circuit implementations of several common neural network algorithms. All circuits described perform in-circuit learning, using Gilbert multipliers as a primary circuit component. These include 3 μm and 1.2 μm designs for contrastive Hebbian learning, and Becker-Hinton networks (a variation of delta-rule learning). In addition, unsupervised learning circuits for competitive learning are presented
