    • An ultra low-power mixed-signal back-end for passive sensor UHF RFID transponders 

      Rodriguez, J.; Delgado Restituto, M.; Masuch, J.; Rodriguez Perez, Alberto; Alarcón Cot, Eduardo José; Rodríguez Vázquez, Ángel (IEEE Press. Institute of Electrical and Electronics Engineers, 2012-02)
      Article
      Accés restringit per política de l'editorial
      This paper describes the design of mixed-signal back end for an ultrahigh-frequency sensor-enabled radio-frequency identification transponder in full compliance with the Electronic Product Code Class-1 Generation-2 protocol, ...

    • CiOpt: a program for optimization of the frequency response of linear circuits 

      Miró Sans, Joan Maria; Palà Schönwälder, Pere (IEEE Computer Society, 1991)
      Text en actes de congrés
      Accés obert
      An interactive personal-computer program for optimizing the frequency response of linear lumped circuits (CiOpt) is presented. CiOpt has proved to be an efficient tool in improving designs where the inclusion of more ...

    • Control de circuitos eléctricos basados en pasividad 

      Sánchez Delgado, Daniel (Universitat Politècnica de Catalunya, 2012-01-26)
      Projecte/Treball Final de Carrera
      Accés restringit per decisió de l'autor
      Este proyecto pretende, a partir de las leyes de Kirchhoff (de tensión y de corriente) y las relaciones constitutivas de los elementos, modelar los circuitos eléctricos lineales en la forma Hamiltoniana con puertos. La ...

    • Ill conditioning loci in noise parameter determination 

      O'Callaghan Castellà, Juan Manuel; Alegret, A.; Pradell i Cara, Lluís; Corbella Sanahuja, Ignasi (IEE-INST ELEC ENG, 1996-08-01)
      Article
      Accés obert
      An analysis of the problem of noise parameter determination is carried out. It is found that the mathematical problem is ill-posed if all the source reflection coefficients (Γs) used in the measurements fall onto a line, ...

    • Loading-effects reduction using a voltmeter in series and an ammeter in parallel 

      Reverter Cubarsí, Ferran (Institute of Electrical and Electronics Engineers (IEEE), 2022-01-01)
      Article
      Accés obert
      This article proposes a method for reducing the loading effects when a dc voltage or current is measured in a linear circuit with a digital multimeter (DMM). In the proposed method, the voltmeter is placed in series to ...

    • Nodal and mesh analysis simplification by introducing a theorem-based preliminary step 

      Reverter Cubarsí, Ferran (2022-11)
      Article
      Accés obert
      This brief proposes a new and simplified method for the analysis of linear circuits that combines the classical mesh-current or node-voltage method with a recently-stated theorem. The beforehand application of such a ...
