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.
