    Multiple split-ring resonators for tri-band filter with asymmetric response
    (Scopus, 2011) Castillo Araníbar, Patricia Raquel; Garcia Lamperez, Alejandro; Segovia Vargas, Daniel; Salazar Palma, Magdalena; Barbin, Silvio
    A triple-band filter composed of multiple split ring resonators is presented. This filter is based on a chain of triple split ring resonators that produces three pass-bands. The change in the dimensions of the corresponding meander lines of the tri-band SRRs can make us obtain an asymmetric response. This response is useful for some microwave applications. This paper presents a study of asymmetric multiband filters based on multiple split ring resonators. © 2011 IEEE.

    Nonlinear device model for GaN and GaAs microwave transistors including memory effects
    (Institute of Electrical and Electronics Engineers Inc., 2015) Rafael Valdivia, Guillermo; Urquizo, Anthony; Mendoza, Thalia; Barbin, Silvio
    In this paper, a new technique for modeling GaN and GaAs transistors is presented. The technique can model one of the most critical phenomena in telecommunications, frequency dispersion effects which is related to memory effects. Results of measurements reveal the accuracy of this technique under small-signal and large-signal conditions. The proposed technique can be embedded into other models to improve its capabilities using only one current source in a new large signal equivalent circuit. © 2015 IEEE.
