±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 ... -
1-V 15-μW 130-nm CMOS super class AB OTA
A super class AB recycling folded cascode amplifier in 130 nm CMOS is presented. It combines for the first time adaptive biasing of the differential input pair, nonlinear current mirrors with current starving and dynamic ... -
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 ... -
200 years diversifying the energy mix? Diversification paths of the energy baskets of European early comers vs. latecomers
The changes in the composition of the energy basket in the long run lead to energy transitions. Primary energy substitution models allow addressing these phenomena. However, the diversification paths of the energy mix of ... -
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 ... -
3D Procedures Manual Included in the App Arsim2care
This manual has been developed within the “ARsim2care: Augmented reality application in clinical simulation” Project funded by the European Union Erasmus + Program, and it is one of the project’s intellectual outputs. The ... -
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 ... -
