±0.25 V Class-AB CMOS capacitance multiplier and precision rectifiers
Reduction of minimum supply requirements is a crucial aspect to decrease the power consumption in VLSI systems. A high performance capacitance multiplier able to operate with supplies as low as ±0.25 V is presented. It is ... -
A 1.2-V current-mode RMS-to-DC converter based on a novel two-quadrant electronically simulated MOS translinear loop
A novel current-mode CMOS RMS-to-DC converter using translinear techniques is introduced. It is based on a squarer/divider cell that is implemented using an electronically simulated loop with a novel biasing scheme that ... -
101 Dothideomycetes genomes: a test case for predicting lifestyles and emergence of pathogens
Dothideomycetes is the largest class of kingdom Fungi and comprises an incredible diversity of lifestyles, many of which have evolved multiple times. Plant pathogens represent a major ecological niche of the class ... -
119Sn Mössbauer spectroscopy for assessing the local stress and defect state towards the tuning of Ni-Mn-Sn alloys
The influence of defects and local stresses on the magnetic properties and martensitic transformation in Ni50Mn35Sn15 is studied at macroscopic and atomic scale levels. We show that both the structural and magnetic properties ... -
150 años de historia de la ética del Trabajo Social en España: periodización de sus valores éticos
Desde que iniciase su andadura como profesión en España, ha quedado constancia del compromiso ético de las y los profesionales del Trabajo Social en las respuestas que han venido ofreciendo en cada época a los conflictos ... -
250 km ultra long remote sensor system based on a fiber loop mirror interrogated by an OTDR
A 253 km ultra long remote displacement sensor system based on a fiber loop mirror interrogated by a commercial OTDR is proposed and experimentally demonstrated. The use of a fiber loop mirror increases the signal to noise ... -
3-D-printed transmit-array antenna for broadband backhaul 5G links at V-band
The low cost and compactness of transmit-array antennas (TAs) make them attractive for 5G backhaul links. However, the TA advantage is less obvious when considering the broadband operation requirement. Two main factors ... -
300 GHz optoelectronic transmitter combining integrated photonics and electronic multipliers for wireless communication
THz communications systems at carrier frequencies above 200 GHz are the key to enable next-generation mobile communication networks with 100 Gbit/s wireless data rates. One of the key questions is, which carrier frequency ... -
360 nW gate-driven ultra-low voltage CMOS linear transconductor with 1 MHz bandwidth and wide input range
A low voltage linear transconductor is introduced. The circuit is a pseudo differential architecture that operates with ±0.2V supplies and uses 900nA total biasing current. It employs a floating battery technique to achieve ... -
A 3D ray launching time-frequency channel modeling approach for UWB ranging applications
Ultrawideband (UWB) has the ability to achieve decimetre level of ranging accuracy, hence, its wider usage nowadays in the field of positioning. In spite of the attractiveness of UWB, its performance is strongly dependent ... -
3D-printed 96 GHz bull’s-eye antenna with off-axis beaming
Reducing the profile, footprint and weight of antennas embarked on aircrafts, drones or satellites has been a long pursued objective. Here we tackle this issue by developing a millimeter-wave 96 GHz elliptical Bull’s-Eye ... -
46-km-long Raman amplified hybrid double-bus network with point and distributed Brillouin sensors
We experimentally demonstrate a 46-km hybrid network that combine point and distributed Brillouin sensors. The proposed sensor network multiplexes low-cost intensity point sensors based on fiber-optic tapers, which are ... -
60 GHz single-layer slot-array antenna fed by groove gap waveguide
A V-band single-layer low-loss slot-array antenna is presented in this letter. Radiating slots are backed by coaxial cavities, which are fed through a groove gap waveguide E-plane corporate feed network. Cavity resonances ... -
77-GHz high-gain bull’s-eye antenna with sinusoidal profile
A high-gain Bull’s-Eye leaky-wave horn antenna working at 77 GHz with sinusoidal profile has been designed, fabricated, and experimentally measured. The influence of the number of periods on the gain and beamwidth is ... -
