      Bogarra Rodríguez, Santiago; Saura Perisé, Jaime; Rolán Blanco, Alejandro (Multidisciplinary Digital Publishing Institute (MDPI), 2022-10-27)
      Article
      Accés obert
      This paper deals with voltage unbalances and how they can be quantified according to the standards. Firstly, a comparison between the different unbalance voltage factors is conducted in order to remark on their divergences. ...
    • Performance of the load-in-the-loop single op-amp voltage controlled current source from the op-amp parameters 

      Macías Lloret, Mario; Seoane, F.; Bragós Bardia, Ramon (2010)
      Text en actes de congrés
      Accés obert
      In recent years, Electrical Bioimpedance (EBI) methods have gained importance. These methods are often based on obtaining impedance spectrum in the range of β-dispersion, i.e. from a few kHz up to some MHz. To measure ...
    • Phase noise degradation of LC-tank VCOs due to substrate noise and package coupling 

      Méndez, M A; Mateo Peña, Diego; Aragonès Cervera, Xavier; González Jiménez, José Luis (IEEE, 2005)
      Text en actes de congrés
      Accés obert
      The present work addresses the investigation of phase noise degradation of LC-tank VCOs due to realistic digitally originated substrate noise. The dominant mechanisms by which this noise is coupled to the output of the ...
    • VCO phase noise and sideband spurs due to substrate noise generated by on-chip digital circuits 

      Méndez Villegas, Miguel Ángel; Osorio Tamayo, Juan Felipe; Mateo Peña, Diego; Aragonès Cervera, Xavier; González Jiménez, José Luis (Institute of Electrical and Electronics Engineers (IEEE), 2006)
      Text en actes de congrés
      Accés obert
      This paper presents the effects of noise generated by realistic digital circuits on RF voltage controlled oscillators (VCO) integrated in the same silicon die. The digital noise is coupled through the common substrate and ...
