Impact of Contact Misalignment on Magnetic Cross Sensitivity of Integrated Vertical Hall Sensors

Autor: Volker Peters, Markus Stahl-Offergeld, Philip Beran, Hans-Peter Hohe, Dennis Krause

Monolithic integration of 3-D Hall effect sensors makes it feasible to measure all three spatial directions of magnetic fields. However, even if the integrated sensors are arranged strictly orthogonal in the semiconductor layout, measurements have sh
