In this paper, we present a new CMOS chip using fuzzy logic controller architecture to control the level of water in a tank. The flow of water (liquid) will be controlled with controllable valves. A motor controls the valve of the tank. The significant aim of this paper is to reduce both motor and input valve amortization and to increase their useful lifetime with presenting a simple and inexpensive...
Presented in this paper is design of the new CMOS circuits to implement Min and Max operators. This work is based on analog advantages such as low die area, high DC range and simplicity which are added to the fuzzy system advantages. For implementing this idea, new current mode circuits are proposed which based on Wilson current mirrors. We used the one of them (min circuit) in implementing inference...
In this paper we design a new Fuzzy Logic controller (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 and three new circuits for implementing Min operators are proposed. We improved a Multiplier/Divider circuit and a...
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...
