Finite-Element Modelling and Analysis of Hall Effect and Extraordinary Magnetoresistance Effect

Hall Effect Modeling in FEM Simulators and Comparison to Experimental Results in Silicon and Printed Sensors

“…Contemporary literature on Hall effect devices seems to favor cross-shaped sensors [7], [39]. However, with more complex sensors and devices being researched and fabricated each day, simulations, such as the ones developed in this thesis, can be powerful tools for IC designers since it allows tuning of material properties and geometry for the theoretical device under investigation.…”

“…Therefore, the magnetic field and its effect on the Hall sensor can still be modeled with this software using an adequate magnetoconductivity model. Sun and Kosel [7] derivation of the magnetoconductivity model is explained next.…”

“…Sun and Kosel present this magnetoconductivity and test their model by applying it to the geometry shown below, in Figure 2-1, to analyze the Hall effect via finiteelement modelling [7]. COMSOL needs a device thickness to extrude the object shown above to measure parameters such as resistance.…”

“…59 between the results from these two methods [7]. 74 Medical's (SJM) pacemakers involves a Hall-effect sensor for the purpose of sensing strong magnetic fields like the ones generated when performing magnetic resonance imaging (MRI).…”
