ABSTRACT:
A method for testing a Hall magnetic field sensor on a wafer includes generating a current flow in a Hall plate of the Hall magnetic field sensor. At least one voltage value across first and second nodes is measured and a measured voltage signal is provided indicative thereof. An electrical resistance based upon the measured voltage and the current is then determined, in the absence of an applied test magnet field.
