Design issues for the VLSI implementation of universal approximator fuzzy systems
(Institute of Electrical and Electronics Engineers, 1999)
Several VLSI realizations of fuzzy systems have been proposed in the literature in the recent years. They employ analog or digital circuitry, offering more or less programmability, implementing difference inference methods, ...

Multi-input voltage and current-mode min/max circuits
(1994)
This paper presents briefly a review of the different algorithms and hardware implementations for multi-input min/max operators. This allow us to show how a clever utilization of MOS devices leads to very simple current ...

A 2.5MHz 55dB Switched-Current BandPass ΣΔ Modulator for AM Signal Conversion
(Institute of Electrical and Electronics Engineers, 1997)
We present a Switched-Current (SI) fourth-order bandpass ΣΔ modulator IC prototype. It uses fully-differential circuits in 0.8μm CMOS technology to obtain a Dynamic Range (DR) larger than 55dB at 2.5MHz center frequency ...

Optimization of adaptive fuzzy processor design
(1998)
A fuzzy processor is programmed to provide anoptimum output for solving a given problem. It could theoretically solve any problem (from a static point of view) if it is an universal approximator. This paper addresses the ...

Current-mode singleton fuzzy controller
(1994)
This paper describes the realization of a fuzzy controller which implements the simplified inference mechanism. CMOS analog circuits where signals are represented as currents are employed. However, the whole system is ...

Building blocks for current-mode implementation of VLSI fuzzy microcontrollers
(1993)
A fuzzy microcontroller is presented implementing a simplified inference mechanism. Fuzzification, rule composition and defuzzification are carried out by means of (basically) analog current-mode CMOS circuits operating ...
