    • Disseny d'un circuit d'interfície per a un PDO aplicat a dispositius piezoelèctrics 

      Fernandez Tomas, Alejandro (Universitat Politècnica de Catalunya, 2015-02-06)
      Treball Final de Grau
      Accés obert
      [ANGLÈS] The digital pulsed oscillators are the systems in charge of controlling a ressonator device so we can get a controlled and constant oscillation. As a control system, it is formed by a circuit that detects the ...

    • Energy efficiency of pulsed actuations on linear resonators 

      Domínguez Pumar, Manuel (2009-12)
      Article
      Accés obert
      The objective of this paper is to show that under some circumstances, the sign of a sampled sinusoid sequences, briefly, is optimal to provide maximum energy transfer to linear resonators in the context of discrete-time ...

    • General dynamics of pulsed digital oscillators 

      Domínguez Pumar, Manuel; Pons Nin, Joan; Ricart Campos, Jordi (IEEE, 2008-02-08)
      Article
      Accés obert
      The objective of this work is to analyze pulsed digital oscillators (PDOs), as dynamical systems. It is proved that under some conditions, the bitstream at the output of the oscillator is that of the sign of a sampled ...

    • Pulsed digital oscillators for electrostatic MEMS 

      Gorreta Mariné, Sergio; Ruiz Fernández, Daniel; Blokhina, Elena; Pons Nin, Joan; Jiménez Serres, Vicente; O'Connell, D.; Feely, Orla; Madrenas Boadas, Jordi; Domínguez Pumar, Manuel (2012)
      Article
      Accés restringit per política de l'editorial
      This paper introduces a new actuation scheme for implementing Pulsed Digital Oscillators (PDOs) for electrostatic MEMS resonators. In this scheme, the capacitance of the device is biased with a voltage and it is periodically ...
