Abstract
It is clear that fuzzy logic is more compatible with analog circuit implementation compare to its digital mate. On the other hand being programmable is very important in various industrial implementations. Because of that this paper introduces a new method for implementing Membership function in fuzzy logic controllers. And a new high-speed analog fuzzification circuit was introduced for implementing this Idea and verified by Hspice simulations. It is characterized by a trapezoidal membership function with independently adjustable parameters. The core of the circuit is a BiCMOS current-mode circuit which works as a fuzzifier. The speed of controller is 20MFILIPS.
Key words: Fuzzifier, fuzzy controller, current-mode circuits, Mixed-Mode and BiCMOS.
