Abstract
A method including: calculating a value of an average phase offset between a first signal and a second signal, wherein: (i) the first signal is generated by one or more first magnetic field sensing elements in response to the magnetic field, (ii) the second signal is generated by one or more second magnetic field sensing elements in response to the magnetic field, and (iii) the magnetic field is associated with a rotating target; storing the value of the average phase offset between the first signal and the second signal at an address in a non-volatile memory of the sensor; when the sensor is restarted, copying the value of the average phase offset from the address in the non-volatile memory to a working memory of the sensor; and using the copy of the value of the average phase offset that is stored in the working memory of the sensor to generate an output signal, the output signal being generated further based on the first signal and the second signal.
