Abstract :
A simple CMOS analogue nonlinear network is presented which can be used as a very efficient means of defining the learning neighbourhood in analogue or digital VLSI realisations of Kohonen maps. The number of components is minimal and the detection of the neighbourhood is facilitated by a steep voltage drop at its boundary.
