Method for measuring noise parameters of microwave two-port
Lázaro Guillén, Antoni; Pradell i Cara, Lluís; O'Callaghan Castellà, Juan Manuel (IEE, 1998-06-30)
Article
Open AccessA new tuner-based method for measuring the four noise-parameters of a two-port is proposed. It makes use of a novel measurement ratio that includes noise powers and mismatch factors simultaneously. In contrast to previous ... -

Noise model of a reverse-biased Cold-FET applied to the characterization of its ENR
Maya Sánchez, Mª del Carmen; Lázaro Guillén, Antoni; Pradell i Cara, Lluís (JOHN WILEY & SONS INC, 2004-02-28)
Article
Open AccessThis paper presents a broadband-noise circuit model for a cold-FET (Vds = 0 V) with a reverse-biased gate. The noise model includes two intrinsic uncorrelated noise-current sources whose spectral densities are determined ... -
Nonlinear actuation model for lateral electrostatically-actuated DC-contact RF MEMS series switches.
Lázaro Guillén, Antoni; Girbau Sala, David; Pradell i Cara, Lluís; Nebot Serra, Àlvar (JOHN WILEY & SONS INC, 2007-06-01)
Article
Open AccessIn this work, a nonlinear model to predict actuation characteristics in lateral electrostatically-actuated DC-contact MEMS switches is proposed. In this case a parallel-plate approximation cannot be applied. The model ... -

Girbau Sala, David; Otegi Urdanpilleta, Nerea; Pradell i Cara, Lluís; Lázaro Guillén, Antoni (IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC, 2006-03-31)
Article
Open AccessThis paper provides a rigorous study of the causes and physical origins of intermodulation distortion (IMD) in RF microelectromechanical systems (MEMS) capacitors, its analytical dependence on the MEMS device design ... -
Tunable dual-band filters based on capacitive-loaded stepped-impedance resonators
Girbau Sala, David; Lázaro Guillén, Antoni; Pérez, A.; Martínez, Ester; Pradell i Cara, Lluís; Villarino Villarino, Ramón (2009)
Conference report
Open AccessThis paper proposes the design of tunable dual-band filters for multi-band multi-standard systems. The main objective is to provide frequency tunability in the second band while maintaining the first band fixed. To this ... -
