Design and performance of CMOS analog fuzzy chips

Abstract

A new approach for implementing a CMOS analog fuzzy processor under the conventional Si wafer processing of the CMOS digital LSI is described. The membership function generator circuit which plays a very important role in the proposed processor has been studied, The defuzzyfication of the combined inference results was performed in the outside digital circuit. The dynamic behavior of fuzzy logic control was visualized on a PC display to evaluate the performance.<>
