Abstract
In one aspect, a magnetic field sensor includes a magnetic field sensing element configured to detect changes in a magnetic field caused by a target and an encoder configured to process signals originating from the magnetic field element. The encoder is configured to generate a first output signal and a second output signal. In a non-fault state, the first and second output signals are 90 electrical degrees out of phase from one another, and in a fault state, the first and second output signals are in phase with each other.
