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.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
