    Article
    Open Access
    A new simple closed-form equation that accurately predicts the effect of an arbitrarily large constant axial load, residual stress or temperature shift on the natural frequencies of an uniform single-span beam, with various ...
  • On the ability of adaptation of speech signals and data hiding 

    Ballesteros, D.M.L.; Moreno Aróstegui, Juan Manuel (2012-11-15)
    Article
    Restricted access - publisher's policy
    The efficient wavelet masking is a scheme of speech-in-speech hiding based on the ability of adaptation of speech signals under the hypothesis “any (speech) secret signal may seem similar to a (speech) host signal if its ...

  • 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)
    Conference lecture
    Restricted access - publisher's policy
    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)
    Article
    Restricted access - publisher's policy
    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 ...
  • Quasi-digital front-ends for current measurement in integrated circuits with giant magnetoresistance technology 

    De Marcellis, A.; Cubells Beltrán, M. Dolores; Reig Escriva, Abilio Càndid; Madrenas Boadas, Jordi; zadov, Boris; Paperno, Eugene; Cardoso, S.; Freitas, P.P. (2014-07-01)
    Article

    In this study, the authors report on two different electronic interfaces for low-power integrated circuits electric current monitoring through current-to-frequency (I-f) conversion schemes. This proposal displays the ...
  • Design of an on–chip linear–assisted DC–DC voltage regulator 

    Cosp Vilella, Jordi; Martínez García, Herminio (Institute of Electrical and Electronics Engineers (IEEE), 2013)
    Conference lecture
    Restricted access - publisher's policy
    This article shows the design of an on-chip CMOS linear-assisted DC-DC regulator. It results a good alternative topology to classic switching DC-DC power converters. In the presented technique, an auxiliary linear regulator ...
  • Field programmable switched-capacitor voltage converter 

    Martínez García, Herminio; Cosp Vilella, Jordi (Institute of Electrical and Electronics Engineers (IEEE), 2014)
    Conference lecture
    Restricted access - publisher's policy
    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 ...
