Abstract
Magnetic field sensors and sensing methods are provided. A magnetic sensor module is configured to measure a magnetic field whose magnitude oscillates between a first extrema and a second extrema. The magnetic sensor module includes a magnetic sensor configured to generate measurement values in response to sensing the magnetic field, and a sensor circuit. The sensor circuit is configured to generate a measurement signal based on the measurement values, compare the measurement signal to a switching threshold, generate a pulsed output signal having pulses that are generated based on the measurement signal crossing the switching threshold, measure a first characteristic of the measurement signal, update an offset of the switching threshold according to an offset update algorithm based on the measured first characteristic of the measurement signal, and selectively enable and disable the offset update algorithm based on at least a second characteristic of the measurement signal.
