Abstract
A CMOS current-mode approach for implementing the defuzzification func tion in analogue fuzzy controllers is proposed. The circuit computes t he centre of area of the output fuzzy conclusion using switched curren t adders and a current divider. Simulation results of the defuzzifier show how the circuit can produce a good approximation of the centre of area even if a small number of levels are used to quantise the output variable,
