    Conference report
    Open Access
    This paper describes a bit-synchronous superregenerative receiver suitable for BPSK demodulation. The output of the superregenerative oscillator (SRO), which reproduces the phase information of the input signal, is ...
  • Bandwidth-length trade-off figures of merit for electro-optic traveling wave modulators 

    Ibarra Fusté, Jose Antonio; Santos Blanco, M. Concepción (2013-05)
    Article
    Open Access
    Closed-form expressions explicitly relating modulation bandwidth and active length in electro-optic traveling wave modulators are presented which fully account for skin-effect electrode loss and optical-electrical wave ...

    Master thesis (pre-Bologna period)
    Open Access
    L'objectiu principal d'aquest projecte és caracteritzar el modulador de polarització electroòptic fabricat amb tecnologia d'òptica integrada. Concretament, es definiran els paràmetres principals del modulador com són el ...
  • Coupled interleaved multicellular parallel converters operated under switching frequency modulation 

    Mon González, Juan; González Díez, David; Gautier, Cirylle; Labrousse, Denis; Costa, François (2014)
    Conference report
    Restricted access - publisher's policy
    The Coupled Interleaved Multicellular Parallel (CIMP) topology is the subject of intense research because of its advantages in terms of systems integration, power density increase, low level of EMI emissions and dynamic ...
  • Design of a modular multilevel converter 

    Abril Castellano, Antoni (Universitat Politècnica de Catalunya, 2013-06)
    Bachelor thesis
    Restricted access - author's decision
    Multilevel converters are power electronics topologies that can generate two or more voltage levels in each output phase. As a result, the voltage and current waveforms generated have lower total harmonic distortion. There ...

  • General dynamics of pulsed digital oscillators 

    Domínguez Pumar, Manuel; Pons Nin, Joan; Ricart Campos, Jordi (IEEE, 2008-02-08)
    Article
    Open Access
    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 ...
