A CAD tool for analog circuit synthesis is presented. This tool, called FASY, uses fuzzy–logic based reasoning to select one topology among a fixed set of alternatives. For the selected topology, a two–phase optimizer sizes all elements to satisfy the performance constrains minimizing a cost function. In FASY, the decision rules used in the...

We have developed a collection of tools for the design, modeling, and test of analog circuits. Sharing a common fuzzy-logic based framework, the tools are part of FASY (Fuzzy-Logic-Based Analog Synthesis), an analog design package developed at the University of Seville. The first tool uses fuzzy logic for topology selection of analog cells. It...

Airfield ground lighting (AGL) systems are responsible for providing visual reference to aircrafts in the airport neighborhood. In an AGL system, a large number of lamps are organized in serial circuits and connected to current regulators that supply energy to the lamps. Controlling and monitoring lamps (including detection and location of...

Partial discharge (PD) analysis has been widely used to detect premature degradation of power cables. Although there are recognized techniques for PD analysis, there is still lack of knowledge about measuring and modeling this phenomenon. This paper proposes a new model based on time domain parameters of the PD signal envelope. The proposed...

En este artículo se presenta la realización sobre FPGA de un circuito con 16 filtros digitales. Un cambio en la entrada es validado cada vez que tres muestras consecutivas toman el mismo valor. El dato muestreado es accesible mediante protocolo VME estándar, incluyendo daisy-cbain para la gestión de interrupciones. El circuito de acceso VME se...
