Abstract
A magnetic field sensor for detecting motion of an object includes threshold generation circuitry and processing. Magnetic field sensing elements are configured to generate a magnetic field signal in response to a magnetic field associated with the object. A motion detector responsive to the magnetic field signal and to a threshold signal is configured to generate a detector output signal having edges occurring in response to a comparison of the magnetic field signal and the threshold signal. A speed detector responsive to the detector output signal generates a speed signal indicative of a speed of motion of the object. A threshold generator responsive to the speed signal generates the threshold signal having a level that varies in response to the speed signal.
