CMOS Realization of a Quantized-Output Classifier Circuit

In this paper a CMOS implementation of a multi-input data classifier with several output levels and a different architecture is presented. The proposed circuit operates in current-mode and can classify several types of analog vector data. The classifier circuit´s new architecture consists of the interconnections of core cells each possessing a current-voltage converter, an inverter followed by a NOR gate and a voltage-current output stage. Using 0.35 mum TSMC technology parameters, SPICE simulation results for a classifier with two inputs are included to verify the expected results.
