A highly efficient composite class-AB–AB Miller op-amp with high gain and stable from 15 pF up to very large capacitive loads
(IEEE, 2018)
Artículo / Artikulua,
In this paper, a highly power-efficient class-AB–AB Miller op-amp is discussed. The structure uses gm enhancement based on local common-mode feedback to provide class-AB operation with enhanced effective gm , open-loop ...
Gas detection using LMR-based optical fiber sensors
(MDPI, 2018)
Artículo / Artikulua,
This work presents a first approach to the utilization of Lossy Mode Resonance (LMR)
based optical fiber sensors for gas detection. The optical sensor is based on a SnO2 thin-film
fabricated onto the core of cladding ...
Steering surface plasmons with a graded index dielectric medium
(IOP Publishing, 2018)
Artículo / Artikulua,
The arbitrary control of surface plasmon (SP) propagation has become an intense research topic for several decades. This is due to the fact that they can be used in a variety of fields such as optical trapping, nanoantennas ...

Dual-mode soft-transition control for single-phase grid-connected photovoltaic inverters
(IEEE, 2018)
Contribución a congreso / Biltzarrerako ekarpena,
Single-phase grid-connected inverters for photovoltaic power generation have been strongly analysed for improvement. Dual-mode control for two-stage inverters makes it possible to improve the efficiency by alternating ...
Labyrinth metasurface absorber for ultra-high-sensitivity terahertz thin film sensing
(Wiley, 2018)
Artículo / Artikulua,
In this work, a labyrinth metasurface sensor operating at the low‐frequency edge of the THz band is presented. Its intricate shape leads to a high electric field confinement on the surface of the structure, resulting in ...
THz sensing with anomalous extraordinary optical transmission hole arrays
(MDPI, 2018)
Artículo / Artikulua,
Subwavelength hole array (HA) metasurfaces support the so-called extraordinary optical transmission (EOT) resonance that has already been exploited for sensing. In this work, we demonstrate the superior performance of a ...
