Current-mode multiple input maximum circuit forfuzzy logic controllers

Abstract

A new current-mode multiple input maximum circuit designed with 2n+1 transistors for n inputs is proposed. The output impedance of this circuit is the same order as that of a Wilson current source. This circuit has been fabricated using 0.8 µm CMOS technology. The experimental result has verified the function of the circuit and shown the merit of high speed and high accuracy.
