Abstract
A semiconductor Hall plate-based sensor can provide information about package stress and can be substantially immune to the influence of magnetic fields. In an example, the sensor can include a Hall plate and an excitation circuit. The excitation circuit can provide signals to respective node pairs of the Hall plate. A measurement circuit can receive information about a first electric signal at a first pair of nodes in response to a first portion of the excitation signal, and can receive information about a second electric signal at a second pair of nodes in response to a second portion of the excitation signal. The first and second electric signals can indicate a charge carrier mobility characteristic of the semiconductor, which can be used to provide an indication of physical stress on the sensor.
