  • Circuit modeling of a MEMS varactor including dielectric charging dynamics 

    Giounanlis, Panagiotis; Andrade Miceli, Dennis; Gorreta Mariné, Sergio; Pons Nin, Joan; Domínguez Pumar, Manuel; Blokhina, Elena (Institute of Physics (IOP), 2016-06-01)
    Article
    Accés obert
    Electrical models for MEMS varactors including the effect of dielectric charging dynamics are not available in commercial circuit simulators. In this paper a circuit model using lumped ideal elements available in the Cadence ...
  • Charge trapping control in MOS capacitors 

    Domínguez Pumar, Manuel; Bheesayagari, Chenna Reddy; Gorreta Mariné, Sergio; López Rodríguez, Gema; Martín García, Isidro; Blokhina, Elena; Pons Nin, Joan (Institute of Electrical and Electronics Engineers (IEEE), 2016-12-26)
    Article
    Accés obert
    This paper presents an active control of C-V characteristic for MOS capacitors based on Sliding Mode control and sigma-delta-modulation. The capacitance of the device at a certain voltage is measured periodically and ...

    Accés restringit per política de l'editorial
    This paper reports and discusses the design and ground tests of a CubeSat payload which allows to measure, in-situ and in real time, the degradation of a polymer of electronic interest due to atomic oxygen etching in LEO. ...
  • Study of resonant modes in a 700 nm pitch macroporous silicon photonic crystal 

    Cardador Maza, David; Vega Bru, Didac; Segura García, Daniel; Rodríguez Martínez, Ángel (2017-01-01)
    Article
    Accés obert
    In this study the modes produced by a defect inserted in a macroporous silicon (MP) photonic crystal (PC) have been studied theoretical and experimentally. In particular, the transmitted and reflected spectra have been ...
  • In situ size sorting in CVD synthesis of Si microspheres 

    Garin Escriva, Moises; Fenollosa Esteve, Roberto; Kowalski, Lukasz (Macmillan Publishers, 2016-12-08)
    Article
    Accés obert
    Silicon microspheres produced in gas-phase by hot-wall CVD offer unique quality in terms of sphericity, surface smoothness, and size. However, the spheres produced are polydisperse in size, which typically range from 0.5¿µm ...
  • Characterization of dielectric charging in MEMS using Diffusive Representation 

    Atienza García, María Teresa; Gorreta Mariné, Sergio; Pons Nin, Joan; Domínguez Pumar, Manuel (Institute of Electrical and Electronics Engineers (IEEE), 2016-09-22)

  • Intermittent chaos for ergodic light trapping in a photonic fiber plate 

    Mariano, Marina; Kozyreff, Gregory; Gerling Sarabia, Luis Guillermo; Romero Gómez, Pablo; Puigdollers i González, Joaquim; Bravo Abad, Jorge; Martorell, Jordi (2016-12-30)
    Article
    Accés obert
    Extracting the light trapped in a waveguide, or the opposite effect of trapping light in a thin region and guiding it perpendicular to its incident propagation direction, is essential for optimal energetic performance in ...
  • Analysis and synthesis of textures through the inference of Boolean functions 

    Domínguez Pumar, Manuel; Torres Urgell, Lluís (1997-05)
    Article
    Accés restringit per política de l'editorial
    This work deals with Boolean functions of non-linear and linear basis. The Boolean random functions of non-linear basis were proposed by Serra (1988,1989). These functions are generated through a Poisson point process upon ...
  • Mechanical properties of Al2O3 inverse opals by means of nanoindentation 

    Roa Rovira, Joan Josep; Coll Valentí, Arnau; Bermejo, Sandra; Jiménez Piqué, Emilio; Alcubilla González, Ramón; Castañer Muñoz, Luis María; Llanes Pitarch, Luis Miguel (2016)
    Article
    Accés restringit per política de l'editorial
    In order to understand the mechanical behaviour of Al2O3 inverse opals, nanoindentation techniques have been implemented in material layers with three different microstructures, in terms of hollow or polystyrene spheres, ...
  • Degradation analysis of thin film photovoltaic modules under outdoor long term exposure in Spanish continental climate conditions. 

    Silvestre Bergés, Santiago; Kichou, Sofiane; Guglielminotti, Letizia; Nofuentes Garrido, Gustavo; Alonso Abella, Miquel (2016-12-01)
