Enhanced single-stage folded cascode OTA suitable for large capacitive loads
(IEEE, 2018)
info:eu-repo/semantics/article,
An enhanced single-stage folded cascode operational
transconductance amplifier able to drive large capacitive loads is
presented. Circuits that adaptively bias the input differential pair
and the current folding stage ...
Smart cities, IoT y salud: retos de Internet of medical things (IoMT)
(Sociedad Española de Informática de la Salud, 2018)
info:eu-repo/semantics/article,
La innovación tecnológica aplicada al ámbito de la salud está permitiendo el rápido desarrollo de la internet de los dispositivos médicos, o en su versión inglesa más aceptada internet of medical things (iomt). En este ...
Computation of traffic time series for large populations of IoT devices
(MDPI, 2018)
Artículo / Artikulua,
En este artículo se estudian las tecnicas para clasificar paquetes de tráfico de red en múltiples clases orientadas a la realización de series temporales de tráfico en escenarios de un elevado numero de clases como pueden ...
Comparison between capacitive and microstructured optical fiber soil moisture sensors
(MDPI, 2018)
Artículo / Artikulua,
Soil moisture content has always been an important parameter to control because it is a
deterministic factor for site-specific irrigation, seeding, transplanting, and compaction detection.
In this work, a discrete sensor ...
Ultra-long (290 km) remote interrogation sensor network based on a random distributed feedback fiber laser
(Optical Society of America, 2018)
info:eu-repo/semantics/article,
In this work, an interferometric sensor has been interrogated 290 km away from the
monitoring station, reaching the longest distance in fiber optic sensing up to date. This has been
attained by employing a double-pumped ...
Tunable deflection and asymmetric transmission of THz waves using a thin slab of graphene-dielectric metamaterial, with and without ENZ components
(Optical Society of America, 2018)
Artículo / Artikulua,
Tunable deflection of obliquely incident, linearly polarized terahertz waves is theoretically studied in a wide frequency range around 20 THz, by combining a thin slab of graphene-dielectric metamaterial (with ten layers ...
Super-oscillatory metalens at terahertz for enhanced focusing with reduced side lobes
(MDPI, 2018)
Artículo / Artikulua,
In this paper, we design and numerically demonstrate an ultra-thin super-oscillatory metalens with a resolution below the diffraction limit. The zones of the lens are implemented using metasurface concepts with hexagonal ...
Super class AB RFC OTA with adaptive local common-mode feedback
(Institution of Engineering and Technology, 2018)
info:eu-repo/semantics/article,
A super class AB recycling folded cascode operational transconductance amplifier is presented. It employs local common-mode feedback using two matched tuneable active resistors, allowing to adapt the amplifier to different ...
An efficient numerical method for singularly perturbed time dependent parabolic 2D convection-diffusion systems
(Elsevier, 2018)
info:eu-repo/semantics/article,
In this paper we deal with solving efficiently 2D linear parabolic singularly perturbed systems of convection–diffusion type. We analyze only the case of a system of two equations where both of them feature the same diffusion ...
Virtual FBGs using saturable absorbers for sensing with fiber lasers
(MDPI, 2018)
info:eu-repo/semantics/article,
The spectral narrowing of Fiber Bragg Gratings (FBGs) introduced by unpumped Er-doped fiber (EDF) was analyzed for fiber lasers (FL). Owing to spatial hole burning (SHB), the spectral response of a virtual FBG can be ...
