Abstract :
In this paper a voltage input-output center of gravity (COG) defuzzifier circuit is designed without using divider in CMOS 0.35 μm process. We have used transconductance amplifier (TCA) structure as a multiplier with voltage-input - current-output for implementation of defuzzifier by exploiting of voltage follower aggregation principle. Good results have been obtained from the point of accuracy and speed.
