Abstract
In this brief, a current-mode Euclidean distance calculator circuit is proposed to play the role of a classifier. This classifier circuit is designed based on a subtracter circuit, an absoluter circuit, a squarer/divider circuit, and a square-rooter/multiplier circuit. The modular design of this classifier allows it to be easily extended for classification application with more input dimensions by doing some proper signal-scaling work due to the dynamic range limited by the square-rooter/multiplier circuit. This classifier circuit has been fabricated with a 0.6-/Ltm single-polysilicon double-metal CMOS process. Both simulation results and measurements of the implemented chip are presented to confirm the function of this classifier.
