DU-TCC 1209: A CMOS IC classifier and its application to IRIS data

A recently built IC which implements a CMOS tunable classifier circuit is introduced and test results of an application are presented. The classifier circuit parameters are determined for Iris data set with an algorithm based on Fisher´s linear discriminant analysis (LDA); the data is first soft then hard classified. The proposed circuit was fabricated using CMOS AMS 0.35 μm process parameters and its performance experimentally tested with Iris data. The layout of the IC also includes current conveyors and current buffers.
