Abstract

An analogue current mode design methodology is presented for the implementation of binary associative memories. Thus, by using the Hamming feedforward network as an example of a binary associative memory and efficiently mapping it into two CMOS-VLSI building block configurations, a prototype artificial neural network (ANN) is developed. The IC building blocks utilize the characteristics of the subthreshold region and converge to a classification in one pass, requiring no feedback. The result is an analog network with the desirable features of high integration, low circuit complexity, and low power dissipation
