  • Design and performance comparison of a superregenerative MPSK transceiver 

    Bonet Dalmau, Jordi; López Riera, Alexis; Palà Schönwälder, Pere; Moncunill Geniz, Francesc Xavier; Babí Oller, Albert (2015)
    Conference lecture
    Open Access
    In this paper we present a superregenerative transceiver able to switch among BPSK, QPSK and 8PSK modulations. An HF-band proof-of-concept transceiver is implemented on an FPGA with a minimum of analog circuitry. The ...
  • Single cycle and transient force measurements in dynamic atomic force microscopy 

    Gadelrab, Karim Raafat; Santos, Sergio; Font Teixidó, Josep; Chiesa, Matteo (2013-11-21)
    Article
    Open Access
    The monitoring of the deflection of a micro-cantilever, as the end of a sharp probe mounted at its end, i.e. the tip, interacts with a surface, forms the foundation of atomic force microscopy AFM. In a nutshell, developments ...
  • Establishing nanoscale heterogeneity with nanoscale force measurements 

    Chang, Yun-Hsiang, Yun-Hsiang; Olukan, Tuza; Lai, Chia-Yun; Santos, Sergio; Lin, Tze-Yu; Apostoleris, Harry; Font Teixidó, Josep; Barcons Xixons, Víctor; Chiesa, Matteo (2015-08-13)

  • Geometric constraint graphs decomposition based on computing graph circuits 

    Joan Arinyo, Robert; Tarres Puertas, Marta Isabel; Vila Marta, Sebastià (Copicentro, 2010-01-01)
    Part of book or chapter of book
    Open Access
    Geometric constraint solving is a growing field which plays a paramount role in industrial applications and that is deeply rooted in automated deduction in geometry. In this work we report on an algorithm to solve ...
  • Periodicity in bimodal atomic force microscopy 

    Lai, Chia-Yun; Barcons Xixons, Víctor; Santos, Sergio; Chiesa, Matteo (American Institute of Physics (AIP), 2015-07-28)
    Article
    Open Access
    Periodicity is fundamental for quantification and the application of conservation principles of many important systems. Here, we discuss periodicity in the context of bimodal atomic force microscopy (AFM). The relationship ...
  • Superregenerative reception of narrowband FSK modulations 

    Palà Schönwälder, Pere; Bonet Dalmau, Jordi; López Riera, Alexis; Moncunill Geniz, Francesc Xavier; Águila López, Francisco del; Giralt Mas, Ma. Rosa (2015-03-01)
    Article
    Open Access
    In this paper we investigate the possibilities of narrowband FSK detection using a superregenerative (SR) receiver. Previous SR FM demodulation techniques rely on detecting the amplitude variations caused by the different ...
  • Forward backward asymmetries of lepton pairs in events with a large transverse momentum jet at hadron colliders 

    Águila López, Francisco del; Ametller Congost, Lluís; Talavera Sánchez, Pedro (2002-10)
    Article
    Open Access
    We discuss forward-backward charge asymmetries for lepton-pair production in association with a large-transverse-momentum jet at hadron colliders. The lepton charge asymmetry relative to the jet direction AjFB gives a new ...
  • A low in-band radiation superregenerative oscillator 

    Palà Schönwälder, Pere; Bonet Dalmau, Jordi; Moncunill Geniz, Francesc Xavier; Águila López, Francisco del; Giralt Mas, Ma. Rosa (2013-05-27)
    Article
    Open Access
    This brief describes a superregenerative (SR) voltage-controlled oscillator as a building block for SR receivers where most of the oscillator spectrum components are outside the reception frequency band. This allows ...
