Open-loop CMOS Current Transducer with Low Temperature Cross-sensitivity

We present an open-loop CMOS current transducer without magnetic core consisting of a bus bar and a CMOS integrated magnetic sensor. The magnetic sensor is a combination of a circular vertical Hall device for low-frequency range and a pick-up coil for high ...

Broadband excitation and indirect detection of nitrogen-14 in rotating solids using Delays Alternating with Nutation (DANTE)

Geoffrey Bodenhausen, Simone Ulzega, Marc Anthony Caporini

A train of short rotor-synchronized pulses in the manner of Delays Alternating with Nutations for Tailored Excitation (DANTE) applied to nitrogen-14 nuclei (I = 1) in samples spinning at the magic angle at high frequencies (typically nu(rot) = 62.5 kHz so ...

Design of a Compact Cylindrical Loudspeaker Array for Spatial Sound Reproduction

Martin Vetterli, Mihailo Kolundzija, Christof Faller

Building acoustic beamformers is a problem whose solution is hindered by the wide-band nature of audible sound. In order to achieve a consistent directional response over a wide range of frequencies, a conventional acoustic beamformer needs a high number o ...

Scalable conformal array for multi-gigabit body centric wireless communication

Mihai Adrian Ionescu, Montserrat Fernandez-Bolanos Badia

In this work a conceptual design of a conformal antenna array is presented for a millimeter-wave antenna system, optimized for low-cost mass production in PCB technology. The conformal array is constituted by four cube faces with two antennas realized on e ...

Brownian motion in a Maxwell fluid

Sylvia Jeney, Matthias Grimm

The equilibrium dynamics of a spherical particle immersed in a complex Maxwell fluid is analyzed in terms of velocity autocorrelation function (VACF), mean-square displacement (MSD), and power spectral density (PSD). We elucidate the role of hydrodynamic m ...

21% efficiency silicon heterojunction solar cells produced with very high frequency PECVD

Christophe Ballif, Antoine Descoeudres, Jonas Geissbühler, Stefaan De Wolf, Loris Barraud, Johannes Peter Seif, Bénédicte Demaurex, Priscille Marguerite Bôle Rothen

Silicon heterojunction solar cells have high open-circuit voltages thanks to excellent passivation of the wafer surfaces by thin intrinsic amorphous silicon (a-Si:H) layers deposited by plasma-enhanced chemical vapor deposition (PECVD). By using in-situ pl ...

Dielectric measurements of tropical wood

Juan Ramon Mosig, Jean-François Zürcher, Olivier Videme Bossou

The aim of this paper is to determine the dielectric characteristics of tropical wood species at microwaves frequency in order to use them as planar antenna substrate. The measurements have been done on dried wood in the frequency range 8.2-12.4 GHz The su ...

A discrete-components impulse-radio UWB Low-Noise Amplifier with voltage controlled-gain

Catherine Dehollain, Edmund James Colli-Vignarelli

We describe an Ultra-Wide Band Low-Noise Amplifier (LNA) with a variable gain that works in the 4.0 GHz to 4.5 GHz frequency range and is made with off-the-shelf discrete components. This LNA has a 30 dB variable gain and a noise figure of 2.2 dB. It was i ...
