Optimization of Integrated Magnetic Field Sensors

Lienemann J., Greiner A., Korvink J.G., Sigmund O., Albert Ludwig University, DE

We present an optimization strategy for the offset reduction of integrated magnetic field sensors with simultaneous maximization of sensitivity. We use the topology optimization method to automatically find a design with maximal sensitivity for given [...]

Offset Analysis in CMOS Magnetotransistors by Numerical Simulation

Metz M., Baltes H., ETH Zürich, CH

Signal offset in magnetotransistors is for the first time analyzed by numerical simulation. Offset needs to be mini-mized to improve the accuracy of low cost CMOS contact-less angle detection systems. The offset is an unwanted [...]

Drain and Gate Voltage Influences on MAGFET Offset and Sensitivity: Modeling and Experiment

Ionescu A.M., Mathieu N., Chovet A., LPCS/ENSERG, FR

In this paper both offset and absolute/relative sensitivities of MAGFET (MAGnetic Field Effect Transistor) are investigated as functions of the drain and gate voltages. Accurate physical and analytical models are developed allowing the identification of [...]
