A novel CMOS analogue fuzzy inference processor

In this paper, we present a design of an analogue fuzzy inference processor with emphasis on the simplicity of architecture, circuitry and implementation. A brief overview of fuzzy inference processor building blocks suitable for hardware implementation using analogue Complementary Metal Oxide Semiconductor (CMOS) techniques is presented. Techniques for generalising the design into an n-rule, n-input fuzzy processor have been established. The design of an analogue fuzzy processor with 4-rule aggregation is discussed, based on a standard 2 μm N-well process
