A fuzzy processor using Josephson junctions

This paper proposes a Josephson fuzzy processor using SQUID gates and the simulation results are illustrated to show how high performance fuzzy processor can be realized by taking into consideration of advantages of Josephson device. The features of the processor proposed here are very simple construction, very high speed operation and ultra low power dissipation. The principle to construct a fuzzy processor using SQUIDs is described in detail and the simulation results for the essential circuit of the fuzzy processor which is composed of more than one hundred SQUIDs are illustrated. These results show that Josephson fuzzy processor which has four rules and sixteen input levels can processor which has four rules and sixteen input levels can perform the fuzzy inferences of 0.79 x 109 times per second
