BiCMOS dynamic defuzzifying circuit for fuzzy logic controllers

Abstract
A BiCMOS dynamic defuzzifying circuit is presented which uses BiCMOS dynamic summation and divider circuits for realising fuzzy logic controllers. Using BiCMOS dynamic circuits, a defuzzifying circuit, designed based on a 2 μm BiCMOS technology, shows a 1.6μs conversion time for converting 64 input fuzzy words into a deterministic value, which is a ×2 improvement in speed as compared with the CMOS circuit.
