A new analog fuzzy logic controller implemented in CMOS technology is
described. The chosen membership function generator keeps the needed a
rea for the inference engine very small while giving a big flexibility
in the configuration of the membership function, The proposed solutio
n for defuzzification gives an additional area reduction over earlier
implementations. High speed, low power fuzzy controller hardware make
the chip appropriate for intelligent sensor application. Simulation re
sults as well as test measurements are presented and discussed to illu
strate the properties and robustness of the proposed circuit.
