A mixed analog-digital fuzzy logic inference processor chip, designed in a 0.35-μmCMOS technology, is presented. The analog fuzzy engine is based on a novel current-mode CMOS circuit used for the implementation of fuzzy partition membership functions. The architecture consists of a 3 inputs-1 output analog fuzzy engine, internal digital registers to store the parameters of the fuzzy controller, and a digital subsystem that allows the programmability of the fuzzy controller via an I2C interface. The architecture, circuits, and some Cadence Spectre simulations are presented.

Abstract
A mixed analog-digital fuzzy logic inference processor chip, designed in a 0.35-μmCMOS technology, is presented. The analog fuzzy engine is based on a novel current-mode CMOS circuit used for the implementation of fuzzy partition membership functions. The architecture consists of a 3 inputs-1 output analog fuzzy engine, internal digital registers to store the parameters of the fuzzy controller, and a digital subsystem that allows the programmability of the fuzzy controller via an I2C interface. The architecture, circuits, and some Cadence Spectre simulations are presented.File in questo prodotto:
