Short CV

Mi trabajo, tanto en docencia como en investigación y desarrollo, ha estado siempre centrado en el diseño de sistemas digitales con circuitos digitales programables de los tipos PLD y FPGA. Más concretamente, he trabajado en los siguientes temas: Estudio de las arquitecturas de PLDs y FPGAs. Seguridad (“safety”) de sistemas de control industriales basados en lógica programable (PLDs y FPGAs). Controladores borrosos (“fuzzy”) basados en FPGAs para su aplicación en convertidores DC_DC conmutados en el sector del automóvil. Algoritmos de control y modulación de convertidores DC_DC multifase realizados mediante FPGAs. Desarrollo de equipos para la enseñanza.
