摘要：

In this paper, we propose several novel hardware circuits that can be used to design fuzzy logic systems. First, five different fuzzifying circuits,which can be easily embedded into other systems, are presented. Then, two novel defuzzifying schemes based on voltage and charge modes are introduced. Transconductance multipliers are employed to implement a voltage-mode defuzzifier while op amplifiers with floating gates are used to realize a charge-mode defuzzifier. Experimental results and layouts of fabricated chips are also presented. Finally, two novel designs of MIN and MAX circuits are discussed. (C) 2000 Elsevier Science Ltd. All rights reserved.
