  • Modified current-mode one-cycle control for linear–assisted DC/DC regulator 

    Martínez García, Herminio; Cosp Vilella, Jordi (Institute of Electrical and Electronics Engineers (IEEE), 2014)
    Comunicación de congreso
    Acceso restringido por política de la editorial
    Linear-assisted DC/DC converters are structures that allow to take advantages of the two classic alternatives in the design of power supply systems: Voltage linear regulators (classic NPN topology or LDO –low dropout–) and ...
  • Speech scrambling based on imitation of a target speech signal with non-confidential content 

    Ballesteros Larrotta, Dora Maria; Moreno Aróstegui, Juan Manuel (2014-05-15)
    Artículo
    Acceso restringido por política de la editorial
    This paper shows a new approach of speech scrambling using imitation to produce a scrambled speech signal with intelligible content. The secret message imitates a target speech signal with non-confidential content through ...

    In this paper we show two different schemes to implement a field programmable circuit that can connect 'n' capacitors as a charge-pump of, eventually, any topology and switching pattern. Capacitor connectivity is configured ...
  • On chaotic behavior in automatic tuning loops for continuous–time filters 

    Martínez García, Herminio; Cosp Vilella, Jordi (Institute of Electrical and Electronics Engineers (IEEE), 2014)
    Comunicación de congreso
    Acceso restringido por política de la editorial
    Continuous–time filters (CTFs) with automatic tuning loops are nonlinear feedback systems with potential instability. Thus, their appropriate linear dynamic modeling should be obtained to assure stability in case of an ...
