    • 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 ...
    • 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 ...
    • 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
      Restricted access - publisher's policy
      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)

    • 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 ...
    • Observation of chaotic behavior in automatic tuning loops for continuous-time filters 

      Martínez García, Herminio; Cosp Vilella, Jordi; Manzanares Brotons, Manuel (Institute of Electrical and Electronics Engineers (IEEE), 2013)
      Conference lecture
      Restricted access - publisher's policy
      he appropriate linear dynamic modeling of continuous-time filters (CTFs) with automatic tuning loops should be obtained to assure stability in case an improved design of the loop controllers is to be carried out. With this ...
    • The imbalance network and incremental evolution for mobile robot nervous system design 

      Olivier, Paul; Moreno Aróstegui, Juan Manuel (2013)
      Conference report
      Restricted access - publisher's policy
      Automatic design of neurocontrollers (as in Evoluationary Robotics) utilizes incremental evolution to solve for more complex behaviors. Also manual design techniques such as task decomposition are employed. Manual design ...
