High-speed ECL circuit for looking up fuzzy control table based on multivalued logic

Starting from the problem of complicated structure and difficult design using digital circuits in hardware implementation of fuzzy control table, a method for converting the fuzzy control table to K-map of multivalued logic and designing fuzzy control table look-up circuit at switch-level using the K-map is proposed. Using the method, the ECL circuit for implementing the table of the universe composed of five elements is designed. The example shows that the method has the characteristics of simple and feasible, and the designed ECL circuit has simple structure and high-speed inference ability.
