Current-Mode CMOS Implementation of a Fuzzy Min-Max Network
نویسندگان
چکیده
Current-mode CMOS implementations of a membership function circuit, min-max operators, and a defuzzifier circuit are proposed in this paper. The programmability of the proposed Gaussian-type function fuzzifier is achieved by varying the gate reference voltages and the sizes of transistors in the differential pairs. A closed-loop control scheme is employed between the fuzzifier and defuzzifier blocks to compensate the normalization of the denominator in the division of a centroid calculation in the defuzzifier block.
