Abstract :
A design of analog CMOS fuzzy operational circuits (a membership function circuit, a maximum circuit, a minimum circuit and a defuzzifier circuit) based on operational transconductance amplifiers (OTAs) is presented. SPICE simulations are given to show their operation speed and accuracy under the assumption that the standard 5 μm CMOS design is used. As an application, a 3×3 singleton fuzzy controller is synthesized using the proposed circuits. The simulation of this controller showed that the operation speed of the order of 1 MFLIPS (fuzzy logical inference per second) is easily realizable
