Abstract: A circuit to detect a movement of an object provides a threshold selection module or a peak identifier module that uses one or more threshold signals identified prior to a present cycle of magnetic field signal in order to establish a threshold signal used for a present cycle of the magnetic field signal. A method associated with the circuit is also described. The circuit and method can be tailored to store values associated with a least common multiple of a set of possible quantities of detectable features on target objects.

Abstract: A magnetic field sensor and associated method provide an output signal with first and second different pulses with first and second different pulse widths indicative of first and second different directions of rotation of a moving target. The magnetic field sensor also includes third pulses with an identifiable encoding to indicate when a signature region in the moving target proximate to the magnetic field sensor passes by the magnetic field sensor. The third pulses each comprise respective state transitions and each comprise respective pulse widths with respective fixed predetermined time durations.

Abstract: A magnetic field sensor includes one or more magnetic field sensing elements configured to generate a magnetic field signal responsive to a magnetic field and a detector coupled to receive an interpolated threshold and a signal representative of the magnetic field signal, wherein the detector is configured to compare the interpolated threshold with the signal representative of the magnetic field signal to generate a detector output signal. A memory is configured to store a first threshold value indicative of a threshold value at a first temperature and a second threshold value indicative of a threshold value at a second temperature lower than the first temperature and a threshold module coupled to the memory and configured to generate the interpolated threshold based on the stored first and second threshold values.
