Common mode response effects in differential measurements
(2021-01)
Article
Open AccessDifferential measurements yield signals that are conditioned by differential or fully differential circuits which output depends on both the differential- and common-mode input voltages. Differential signals carry the ... -
Assessment of emotional states through physiological signals and Its application in music therapy for disabled people
(Institute of Electrical and Electronics Engineers (IEEE), 2020-07-09)
Article
Open AccessDisabled people have more difficulties for expression and interaction on a non-verbal level because of the physical, sensory or communication difficulties that they usually present. Regarding music therapy, the existing ... -
Adquisición y tratamiento de datos para la caracterización de las acciones dinámicas en los disipadores de energía hidráulica
(1992-02)
Article
Open AccessLas características de tridimensionalidad, turbulencia anisotrópica y no homogénea que se presentan en el flujo de los disipadores de energía hidráulica, no permiten un estudio analítico del problema, siendo por tanto la ... -
Micro air vehicles energy transportation for a wireless power transfer system
(2019-10-22)
Article
Open AccessThe aim of this work is to demonstrate the feasibility use of an Micro air vehicles (MAV) in order to power wirelessly an electric system, for example, a sensor network, using low-cost and open-source elements. To achieve ... -
Cost-effective autonomous sensor for the long-term monitoring of water electrical conductivity of crop fields
(2019-10-01)
Article
Open AccessSalinity is a key parameter determining water quality. In agriculture, irrigation water with high salinity levels impacts plant growth and yield negatively hence there is a need to monitor it and irrigate with fresh water ... -
A Fully Differential Synchronous Demodulator for AC Signals
(2019-02-22)
Article
Restricted access - publisher's policyA novel fully differential (FD) demodulator is presented. Using different design strategies, the circuit can be used for processing amplitude-modulated (AM) signals obtained from impedance measurements or coming from ... -
Comments on “A novel high input impedance front-end for capacitive biopotential measurement”
(Springer, 2019-12-13)
Article
Open AccessA front-end for biopotential sensing in wearable medical devices has been recently proposed which is claimed to provide 100 GOinput impedance by manually matching two resistor pairs in a positive- and a negative-feedback ... -
Common mode electronic noise in differential circuits
(2019-07-01)
Article
Open AccessDifferential circuits are assumed to reject common-mode noise yet no parameter is available to describethat rejection as the Common Mode Rejection Ratio (CMRR) applies only to deterministic signals, not torandom noise. We ... -

Solar energy radiation measurement with a low–power solar energy harvester
(2018-08-01)
Article
Open AccessSolar energy radiation measurements are essential in precision agriculture and forest monitoring and can be readily performed by attaching commercial pyranometers to autonomous sensor nodes. However this solution significantly ... -
Time-Division Multiplexing Control of Multi-Input Converters for Low-Power Solar Energy Harvesters
(Institute of Electrical and Electronics Engineers (IEEE), 2018-03-29)
Article
Open AccessMany autonomous sensor nodes use small photovoltaic (PV) panels oriented towards the direction that provides the highest energy yield in the worst-case scenario. Since all those panels operate at similar irradiance and ... -
