Abstract :
We describe an analogue VLSI circuit which implements the radial basis function (RBF) algorithm, based around a compact Euclidean Distance calculator. A prototype chip has been fabricated and tested. First, we describe the RBF architecture and present results from the test chip. We then discuss the impact of device variations, which traditionally cause problems for analogue systems. Finally, we discuss the scaling of our results from the small test chip to a full-sized RBF system
