New Components for Building Fuzzy Logic Circuits

This paper presents two new designs of fuzzy logic circuit components. Currently due to the lack of fuzzy components, many fuzzy systems cannot be fully implemented in hardware. We propose the designs of a new fuzzy memory cell and a new fuzzy logic gate. Unlike a digital memory cell that can only store either a zero or a one, our fuzzy memory cell can store any value ranging from zero to one. The fuzzy memory cell can also be used as a D-type fuzzy flip-flop, which is the first design of a D-type fuzzy flip-flop. We also designed a new fuzzy NOT gate based only on digital NOT gates that can easily be implemented in CMOS microchips. Our D-type fuzzy flip-flop and fuzzy NOT gate together with fuzzy AND gate and fuzzy OR gate allow us to design and implement fuzzy logic circuits to fully exploit fuzzy paradigms in hardware.
