    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

    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)

    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

    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)
    Conference lecture

    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 ...
  • Comparison and adaptation of step length and gait speed estimators from single belt worn accelerometer positioned on lateral side of the body 

    Sayeed, Taufique; Samà Monsonís, Albert; Català Mallofré, Andreu; Cabestany Moncusí, Joan (2013)
    Conference lecture

  • A heterogeneous database for movement knowledge extraction in Parkinson's disease 

    Samà Monsonís, Albert; Pérez López, Carlos; Rodríguez Martín, Daniel Manuel; Cabestany Moncusí, Joan; Moreno Aróstegui, Juan Manuel; Rodríguez Molinero, Alejandro (2013)
    Conference lecture
    Open Access
    This paper presents the design and methodology used to create a heterogeneous database for knowledge movement extraction in Parkinson's Disease. This database is being constructed as part of REM- PARK project and is ...
