Abstract
We report the modeling and optimization of a novel split current Hall device. A unique advantage of the device is the reduction of the common mode sensor signal while the absolute sensitivity is kept. This is achieved by an additional current terminal. Numeric modeling with our finite element package SOLIDIS allows to separate the influence of the geometry and that of material properties on the sensitivity. We achieved an accuracy better than 5% with respect to the measurement data. Based on these results we optimized the device for maximum sensitivity and investigated the influence of several geometric parameters.
