On the efficient implementation of SDA for boxed strip-like and slot-like structures
(Institute of Electrical and Electronics Engineers, 1998)
This paper reports on an enhanced implementation of the spectral-domain analysis (SDA) of boxed multistrip or multislot transmission lines embedded in a layered medium, including biaxial materials. Very high numerical ...

Integrated circuit implementation of fuzzy controllers
(Institute of Electrical and Electronics Engineers (IEEE), 1996)
This paper presents mixed-signal current-mode CMOS circuits to implement programmable fuzzy controllers that perform the singleton or zero-order Sugeno’s method. Design equations to characterize these circuits are provided ...

Learning under hardware restrictions in CMOS fuzzy controllers able to extract rules from examples
(Universidad de Granada. Departamento de Ciencias de la Computación e Inteligencia Artificial, 1996)
Fuzzy controllers are able to incorporate knowledge expressed in if-then rules. These rules are given by experts or skilful operators. Problems arise when there are no experts or/and rules are not easy to find. Author's ...

Mixed-signal design of a fully parallel fuzzy processor
(Institute of Electrical and Electronics Engineers, 1998)
The authors present a novel architecture for implementing general-purpose fuzzy chips which allows fully-parallel rule processing employing a reduced number of mixed-signal computing blocks and minimum-sized digital memories. ...

Thermal and electrohydrodynamic plumes: a compartive study
(AIP Publishing, 1996)
This paper deals with self similar thermal and electrohydrodynamic (EHD) plumes. The former arises from hot lines or points, whereas the latter arises when sharp metallic contours submerged in non conducting liquids ...

Quick quasi-TEM analysis of multiconductor transmission lines with rectangular cross section
(Institute of Electrical and Electronics Engineers, 1997)
This paper presents an efficient and accurate procedure for computing the quasi-static matrix parameters ([C], [L], [G], and [R]) of rectangular-shaped conductors embedded in a multilayered dielectric medium over an infinite ...
Article
Self-checking current-mode analogue memory
(Institute of Electrical and Electronics Engineers, 1997)
A long-term analogue memory based on continuous-time, currentmode algorithmic A/D-D/A converters is presented. It achieves an efficient performance in terms of speed, resolution, power, and area, while incorporating a ...
Article
Towards the IC implementation of adaptive fuzzy systems
(Institute of Electronics, Information and Communication Engineers, 1998)
The required building blocks of CMOS fuzzy chips capable of performing as adaptive fuzzy systems are described in this paper. The building blocks are designed with mixed-signal current-mode cells that contain low-resolution ...
Article
A mixed-signal architecture for high complexity CMOS fuzzy controlers
(Universidad de Granada: Departamento de Ciencias de la Computación e Inteligencia Artificial, 1999)
Analog circuits provide better area/power efficiency than their digital counterparts for low-medium precision requirements [1]. This limit in precision, as well as the lack of design tools when compared to the digital ...
