In this paper a new CMOS classifier circuit is presented, simulated, and compared with other recently introduced circuits. The proposed CMOS circuit operates in current-mode and can classify several types of data. The architecture is designed using two threshold circuits and a subtraction circuit. Among many possible applications of the classifier circuit, template-based pattern classification, namely template matching and character recognition with corruption, and in another direction its use as a quantizer are given. Using 0.35- µm AMS technology parameters, SPICE simulations as well as hard realization results for the classifier and application circuits are included; detailed Monte Carlo analyses to assess parameter mismatch effects are also performed.
