Silicon carbide as a material-based high-impedance surface for enhanced absorption within ultra-thin metallic films
(Optical Society of America, 2020)
info:eu-repo/semantics/article,
The absorption of infrared radiation within ultra-thin metallic films is technologically relevant for different thermal engineering applications and optoelectronic devices, as well as for fundamental research on sub-nanometer ...
Energy-efficient amplifiers based on quasi-floating gate techniques
(MDPI, 2021)
Artículo / Artikulua,
Energy efficiency is a key requirement in the design of amplifiers for modern wireless applications. The use of quasi-floating gate (QFG) transistors is a very convenient approach to achieve such energy efficiency. We ...
Super-gain-boosted AB-AB fully differential Miller op-amp with 156dB open-loop gain and 174MV/V MHZ pF/uW figure of merit in 130nm CMOS technology
(IEEE, 2021)
Artículo / Artikulua,
A fully differential Miller op-amp with a composite input stage using resistive local common-mode feedback and regulated cascode transistors is presented here. High gain pseudo-differential auxiliary amplifiers are used ...
Sub-synchronous resonance damping control strategy for DFIG wind turbines
(IEEE, 2020)
info:eu-repo/semantics/article,
Doubly-fed induction generator (DFIG) wind turbines connected to capacitive series-compensated transmission lines are prone to exhibit oscillatory behavior. The phenomena is called sub-synchronous resonances (SSRs), as ...
Synthetic wind speed generation for the simulation of realistic diurnal cycles
(IOP Publishing, 2020)
info:eu-repo/semantics/conferenceObject,
Synthetic wind-speed generators can provide a detailed characterisation of the wind variability at different time scales. A keen interest in the availability of synthetic wind speeds has recently risen in wind power modelling ...
Propagation models in vehicular communications
(IEEE, 2021)
info:eu-repo/semantics/article,
In the advent of becoming reality, the era of autonomous vehicles is closer than ever, and with it, the need for faster and reliable wireless connections. The propagation channel determines the performance limits of wireless ...
Towards sub-meter level UWB indoor localization using body wearable sensors
(IEEE, 2020)
info:eu-repo/semantics/article,
Thanks to its ability to provide sub-meter level positioning accuracy, Ultrawideband (UWB) has found wide use in several wireless body area network (WBAN) applications such as ambient assisted living, remote patient ...
Soft surfaces and enhanced nonlinearity enabled via epsilon-near-zero media doped with zero-area perfect electric conductor inclusions
(Optical Society of America, 2020)
info:eu-repo/semantics/article,
Introducing a dielectric inclusion inside an epsilon-near-zero (ENZ) host has been shown to dramatically affect the effective permeability of the host for a TM-polarized incident wave, a concept coined as photonic doping ...
Low-power wide-bandwidth CMOS indirect current feedback instrumentation amplifier
(Elsevier, 2020)
info:eu-repo/semantics/article,
The analysis and design trade-offs of a simple and economical technique to implement wideband low-voltage CMOS instrumentation amplifiers (IAs) based on indirect current feedback (ICF), are described. The input and an ...
Straightforward nano patterning on optical fiber for sensors development
(Optical Society of America, 2020)
info:eu-repo/semantics/article,
A simple method to prepare a nano pattern along the surface of an optical fiber is applied in this Letter to develop a pH sensor. The template is made of a block copolymer that defines specific locations where gold nano ...
