    Open Access
    Graphene is a promising material which has been proposed to build graphene plasmonic miniaturized antennas, or graphennas, which show excellent conditions for the propagation of Surface Plasmon Polariton (SPP) waves in the ...
  • Capacitorless DC-DC regulator as a candidate topology for photovoltaic solar facilities 

    Martínez García, Herminio (2015-03)
    Article
    Open Access
    Linear-assisted DC/DC converters (or linearswitching hybrid DC/DC converters) consist of a voltage linear regulator (classic NPN or nMOS topologies and LDO) connected in parallel with a switching DC/DC converter. They are ...
