Characterization and modeling of the capacitive HBC Channel
(IEEE, 2015) Artículo / Artikulua
The increasing interest in wireless body area networks has created the need for alternative communication schemes. One example of such schemes is the use of the human body as a communication medium. This technology is ... -
Characterization of RF-MOSFETs in common-source configuration at different source-to-bulk voltages from S-parameters
(IEEE, 2013) Artículo / Artikulua
Using a new test fixture that allows us to bias the bulk terminal through an additional compensated DC probe, a two-port S-measurement-based methodology to characterize RF-MOSFETs in common-source configuration is herein ... -
Consistent modeling and power gain analysis of microwave SiGe HBTs in CE and CB configurations
(IEEE, 2015) Artículo / Artikulua
This paper presents a methodology to model SiGe HBTs biased in common-emitter and in common-base configurations including the bias-dependent substrate parasitics, which allows determining the more suitable configuration ... -

Contribución a congreso / Biltzarrerako ekarpena
Rectangular waveguide commensurate-line stepped-impedance bandpass filters have been shown to have an increased fabrication robustness using conventional CNC milling. In this paper, their frequency response is improved by ... -
Magnetic human body communication based on double-inductor coupling
(IEEE, 2017) Contribución a congreso / Biltzarrerako ekarpena
This paper proposes a new technique for Human Body Communication (HBC) that uses the magnetic coupling in transmitter and receiver. A discussion about the presence of parasitic paths, when magnetic coupling is used in the ... -
Modeling and parameter extraction of test fixtures for MOSFET on-wafer measurements up to 60 GHz
(Wiley, 2013) Artículo / Artikulua
We present a circuit model and parameter determination methodology for test fixtures used for on-wafer S-parameter measurements on CMOS devices. The model incorporates the frequency dependence of the series resistances and ... -
Modeling ground-shielded integrated inductors incorporating frequency-dependent effects and considering multiple resonances
(IEEE, 2019) Artículo / Artikulua
A model for integrated spiral inductors which incorporates the physically expected frequency-dependent effects modifying the device's impedance is proposed. Moreover, it is demonstrated that the effect of resonances occurring ... -
Temperature measurements on overhead lines using fiber Bragg grating sensors
(IEEE, 2017) Capítulo de libro / Liburuen kapitulua
This paper shows the results of temperature measurements on an overhead power transmission line segment under controlled conditions using Fiber Bragg Grating (FBG) sensors. An optical fiber with three FBG sensors enclosed ... -
Using S-parameter measurements to determine the threshold voltage, gain factor, and mobility degradation factor for microwave bulk-MOSFETs
(Elsevier, 2011) Artículo / Artikulua
In this paper, we present an extraction and characterization methodology which allows for the determination, from S-parameter measurements, of the threshold voltage, the gain factor, and the mobility degradation factor, ...
