خلاصه مقاله:

In this paper a design of an analogue defuzzifer circuit based on mtiltiplier and divider circuits to realize the center-of-grattity defuzzification
strategy is described. The current -mode approach allows it to operate in 3 3v with low power consumption. Input of this circtril is current while output is voltage. This circuit ,s independenot f MOS transistor devicep arametersd nd it can be easily expandedforfuzzy circuit'tvith more rales. The presented circuit has been simtilated on HSPICE and the rewlts shotved that it can operate at high speed with lott power consumption.
