Automatic jitter measurement in needle-detected motor unit potential trains
(Elsevier, 2022)
Artículo / Artikulua,
In an active motor unit (MU), the time intervals between the firings of its muscle fibers vary across successive MU
activations. This variability is called jitter and is increased in pathological processes that affect the ...
Control design and stability analysis of power converters: the discrete generalized Bode criterion
(IEEE, 2021)
Artículo / Artikulua,
For the controller design and stability analysis of power electronic converters, the Bode stability
criterion and its subsequent revisions are the most practical tools. However, even though the control of the
power ...
AC coupled amplifier with a resistance multiplier technique for ultra-low frequency operation
(Elsevier, 2022)
Artículo / Artikulua,
This paper proposes a novel, tunable AC coupled capacitive feedback amplifier, exhibiting an ultra-low high pass corner frequency. This is accomplished by actively boosting the output resistive value of a MOS transistor ...
Integrating multiple stubs in stepped-impedance filter aiming for high selectivity
(IETWiley, 2022)
Artículo / Artikulua,
A design technique to include multiple and fully-controlled transmission zeros (TZs) in the frequency response of rectangular waveguide commensurate-line stepped-impedance filters is presented in this letter. These bandpass ...
High gain/bandwidth off-chip antenna loaded with metamaterial unit-cell impedance matching circuit for sub-terahertz near-field electronic systems
(Springer, 2022)
Artículo / Artikulua,
An innovative of-chip antenna (OCA) is presented that exhibits high gain and efciency performance
at the terahertz (THz) band and has a wide operational bandwidth. The proposed OCA is implemented
on stacked silicon layers ...
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 ...
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 ...
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 ...
The effect of a multicomponent intervention on steatosis is partially mediated by the reduction of intermuscular abdominal adipose tissue in children with overweight or obesity: the EFIGRO Project
(American Diabetes Association, 2022)
Artículo / Artikulua,
OBJECTIVE: In adults, there is evidence that improvement of metabolic-associated fatty liver disease (MAFLD) depends on the reduction of myosteatosis. In children, in whom the prevalence of MAFLD is alarming, this muscle-liver ...
A 3-D indoor analysis of path loss modeling using kriging techniques
(IEEE, 2022)
Artículo / Artikulua,
This study proposes a novel measurement-based method to predict and model three-dimensional (3-D) path loss in indoor scenarios, which first regresses 28 GHz measurements via median path loss modeling and then includes ...
