Kohonen maps are self-organizing neural networks that classify and quantify n-dimensional data into a one- or two-dimensional array of neurons. Most applications of Kohonen maps use simulations on conventional computers, eventually coupled to hardware accelerators or dedicated neural computers. The small number of different operations involved in the(More)
This survey of the pros and cons of analog devices presents a 14-neuron test chip and an algorithm for fully interconnected networks. S ince the pioneering work of McCulloch and Pitts in 1943,' many researchers have tried to realize artificial devices that emulate the human brain. The challenge is to obtain a computational power unknown to conventional von(More)
Redundancy in the output code, as instrument to reduce the impact of non-idealities in different architectures of two-step A to D converters, is investigated. A circuit model capable of providing an estimate of the required sizes for passive components for a given accuracy was developed. Such model represents an useful design tool, providing a way to(More)
