Measurement of on-wafer transistor noise parameters without a tuner using unrestricted noise sources
(HORIZON HOUSE PUBLICATIONS INC, 2002-03-31)
Article
Accés obertThe authors present a method for calibrating the four noise parameters of a noise receiver which does not require a tuner The method permits using general (mismatched) noise sources, which may present very different source ... -

Method for measuring noise parameters of microwave two-port
(IEE, 1998-06-30)
Article
Accés obertA 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
(JOHN WILEY & SONS INC, 2004-02-28)
Article
Accés obertThis 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.
(JOHN WILEY & SONS INC, 2007-06-01)
Article
Accés obertIn 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 ... -

Study of intermodulation in RF MEMS variable capacitors
(IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC, 2006-03-31)
Article
Accés obertThis 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
(2009)
Text en actes de congrés
Accés obertThis 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 ... -
Tunable dual-band resonators for communication systems
(2010-06-01)
Article
Accés restringit per política de l'editorialThis paper proposes the design of tunable dual-band resonators for multi-band multi-standard systems. The main objective is to provide frequency tunability in the second resonance while maintaining the first resonance ...
