Abstract
A method for verifying an operation of a Hall-effect sensor without an applied magnetic field. The method can include providing a bias signal to a first pair of terminals of a Hall-effect element, applying a Hall current signal to a second pair of terminals of the Hall-effect element, measuring a Hall output voltage across the second pair of terminals and comparing the measured Hall output voltage to an expected Hall output voltage that would be provided by a corresponding applied magnetic field.
