A Modification in Euclidean Distance Calculator Circuit with the Aim of English-Numeral Recognition

Zeinab Delirian; Dr. Masoud Jabbari; Mohamadbagher Sharifnia

In this brief, a current-mode Euclidean distance calculator circuit which acts as a numeral recognizer is proposed. This recognizer circuit consists of three sub-circuits: a subtracter-rectifier circuit, a squarer/divider circuit, and a geometric-mean circuit. This recognizer can be easily extended for other applications with more input dimensions such as character recognition. Designed circuits were simulated using HSPICE by level 49 parameters in 0.35µm standard CMOS technology. Simulation results have shown better accuracy and lower power in comparison with the previous works.
