Abstract
A magnetic field sensor includes a comparator coupled to receive a calculated threshold value based upon a temperature signal, a stored value of a temperature coefficient signal, and a stored value of a measure threshold signal, and also coupled to receive a signal representative of a magnetic field signal. The comparator is configured to compare the calculated threshold value with the signal representative of the magnetic field signal to generate an output signal. A corresponding method is associated with the magnetic field sensor.
