  • Magnetic field sensor with an adjustable threshold
    Patent number: 11454521
    Abstract: A magnetic field sensor for detecting motion of an object includes one or more magnetic field sensing elements configured to generate a magnetic field signal in response to a magnetic field associated with the motion of the object and a detector responsive to the magnetic field signal and to a threshold signal and configured to generate a comparison signal having edges occurring in response to a comparison of the magnetic field signal to the threshold signal. A threshold generator is configured to generate the threshold signal at a first level when a peak-to-peak value of the magnetic field signal is greater than a first predetermined value and at a second level when the peak-to-peak value of the magnetic field signal is less than a second predetermined value different than the first predetermined value.
