Abstract :
Presented in this paper is design of a new FLC chip with mixed-signal input and digital output. For implementing this idea, a new programmable Fuzzifier circuit based on generation of three current membership functions including Gaussian, Trapezoidal and Triangular shapes is proposed. We improved a current mode Analog to Digital (A/D) converter with 7bit resolutions to complete and implement Defuzzifier block. The proposed controller was designed less than 0.1 mm2 in 0.35um CMOS standard technology. The inference speed of the controller is about 16.6 MFLIPS too.
