Predictive calibration technique for magnetic field position sensors

Catherine Dehollain

In this paper, we present a calibration technique for controlling the magnetic field emitted by an antenna without measuring that magnetic field or the current through the antenna. Using a predictive algorithm and without adding hardware to perform test me ...

Electromagnetic Model of an Ironless Inductive Position Sensor

Yves Perriard, Alessandro Danisi, Alessandro Masi

An ironless position sensor is a novel sensing structure which exhibits intrinsic immunity to external magnetic fields, since it is characterized by air-cored supply and sensing windings. This new solution may be of significant interest for applications wh ...

Power Distribution Solutions for Large Hadron Collider Upgrades

Stefano Michelis

In view of the Large Hadrons Collider experiments upgrade, where the inner front-end electronics will require higher supply power, a new power distribution scheme has to be designed. This thesis presents a new and more efficient scheme based on step-down D ...

Possible skyrmion-lattice ground state in the B20 chiral-lattice magnet MnGe as seen via small-angle neutron scattering

Jonathan White

We have investigated the magnetic structure in a polycrystalline sample of the B20-type MnGe by means of small-angle neutron scattering. On the projected diffraction plane normal to the incoming neutron beam, a Debye-ring-like pattern appears due to the ra ...

K-band single-chip electron spin resonance detector

Jens Anders

We report on the design, fabrication, and characterization of an integrated detector for electron spin resonance spectroscopy operating at 27 GHz. The microsystem, consisting of an LC-oscillator and a frequency division module, is integrated onto a single ...

Magnetization Reversal Dynamics in Ferromagnetic Semiconductors

Liza Herrera Diez

This thesis is dedicated to the study of the magnetization reversal dynamics in compressively strained (Ga,Mn)As and differently functionalized (Ga,Mn)As materials. In the first part the domain wall dynamics of pure (Ga,Mn)As/GaAs materials is in the focus ...

High Bandwidth CMOS Magnetic Sensors Based on the Miniaturized Circular Vertical Hall Device

Mirjana Banjevic

Hall-effect devices make up by far the largest part of all magnetic sensors on the market today. The main reason is compatibility of Hall devices with modern semiconductor technology. In particular, integrated Hall sensor micro-systems fabricated in low-co ...

Nested Surface Coils for Multinuclear NMR

Rolf Gruetter

This article introduces the design of surface coils for multinuclear applications. The relative sensitivities of several NMR-visible nuclei of biological interest are considered, and the motivations to operate an RF coil at multiple frequencies, both seque ...

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

Radivoje Popovic, Mirjana Banjevic

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 ...

A closed core microfluxgate sensor with cascaded planar FeNi rings

Pavel Kejik, Ozge Zorlu

In this paper, we present a new microfabricated fluxgate sensor structure using cascaded planar rings as the ferromagnetic core. The planar ring structures provide closed magnetic excitation loops enabling uniform core saturation with relatively small exci ...
