A fuzzy controller using switched-capacitor techniques

The use of switched-capacitor (SC) techniques to build a fuzzy controller is discussed. This is carried out at two levels: architecture, and cell design. Using a sequential architecture, the required building blocks are introduced and its realization is described. An advantage of this approach is the compatibility with sound analog techniques that can help in the design of the defuzzifier. The proposed system can be considered as a starting point for exploring the capabilities offered by SC networks for the hardware implementation of future fuzzy systems.<>
