Current-mode analogue defuzzifier
Francisco J. Pelayo, Ignacio Rojas, Julio Ortega, A. Prieto · Electronics Letters · 1993
A CMOS current-mode approach for implementing the defuzzification function in analogue fuzzy controllers is proposed. The circuit computes the centre of area of the output fuzzy conclusion using switched current 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.
