Folded Cascode OTA with 5540 MHzpF/mA FoM
(IEEE, 2018)
info:eu-repo/semantics/conferenceObject,
A micropower single-stage folded cascode amplifier able to drive a wide range of capacitive loads is presented. It features class AB operation and includes power-efficient adaptive biasing techniques, which provide enhanced ...
On the optimal current followers for wide-swing current-efficient amplifiers
(IEEE, 2018)
info:eu-repo/semantics/conferenceObject,
The design of various current followers for the implementation of OTAs with high slew rate and current efficiency is addressed. Two basic current follower topologies are compared, and modifications of both followers to ...
Study on antenna mutual coupling suppression using integrated metasurface isolator for SAR and MIMO applications
(IEEE, 2018)
info:eu-repo/semantics/conferenceObject,
A metasurface based decoupling structure that is composed of a square-wave slot pattern with exaggerated corners that is implemented on a rectangular microstrip provides high-isolation between adjacent patch antennas for ...
Mutual-coupling reduction in metamaterial substrate integrated waveguide slotted antenna arrays using metal fence isolators for SAR and MIMO applications
(IEEE, 2018)
info:eu-repo/semantics/conferenceObject,
A new type of mutual coupling reduction technique is applied to metamaterial substrate integrated waveguide (SIW) slotted antenna array. The circular shaped reference SIW antenna array is constructed from Alumina substrate ...
Integration of autonomous wireless sensor networks in academic school gardens
(MDPI, 2018)
info:eu-repo/semantics/article,
In this work, the combination of capabilities provided by Wireless Sensor Networks (WSN) with parameter observation in a school garden is employed in order to provide an environment for school garden integration as a ...
Fast and robust ellipse detection algorithm for head-mounted eye tracking systems
(Springer, 2018)
info:eu-repo/semantics/article,
In head-mounted eye tracking systems, the correct detection of pupil position is a key factor in estimating gaze direction.
However, this is a challenging issue when the videos are recorded in real-world conditions, due ...
Real time measuring system of multiple chemical parameters using microstructured optical fibers based sensors
(IEEE, 2018)
info:eu-repo/semantics/article,
In this paper, a multiplexing system for simultaneous interrogation of optical fiber sensors which measure different parameters is presented and validated. The whole system has been tested with 6 different sensing heads ...
Watt-level green random laser at 532 nm by SHG of Yb-doped fiber laser
(Optical Society of America, 2018)
info:eu-repo/semantics/article,
We have developed a Watt-level random laser at 532 nm. The laser is based on a 1064 nm random distributed ytterbium-gain assisted fiber laser seed with a 0.35 nm line-width and 900 mW polarized output power. A study for ...
3-D printed horn antennas and components performance for space and telecommunications
(IEEE, 2018)
Artículo / Artikulua,
In this work, a study of the performance of several
antennas and components, manufactured using an accurate
stereolithography 3D printer and resin for maximum accuracy
and detail, is carried out. Electroless plating of ...
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 ...
