Abstract
A new Euclidean distance circuit focused on high-speed operation will be presented in this paper. The computing accuracy will be improved compensating the error introduced by the second-order effects, which affect MOS transistor operation (short channel effect and mobility degradation) by a proper common-mode input voltage excitation of the squarer circuit. Because the elementary approach of designing an Euclidean distance circuit (exclusively based on classical MOS transistors in saturation) requires an additional threshold voltage extractor circuit, the new proposed idea is to use a FGMOST (Floating Gate MOS Transistor), having the advantage of a very large reducing of the circuit complexity.
