Abstract:
Various embodiments discussed herein can comprises systems or methods that can improve over existing spinning current Hall sensor systems via at least one of interleaving spinning phases or sliding averaging/summing. One example embodiment can comprise a sensor system comprising M (a positive integer) spinning current Hall sensors, each of which has N (an integer greater than one) distinct spinning phases during which it can acquire sensor data, and a multiplexer that can select sensor data of the sensors according to a M×N spinning phase sensor sequence. The M×N distinct spinning phases of the sensor sequence can be interleaved, wherein the average in the time domain of the N spinning phases for each sensor is the same. For each of the M sensors, a sum and/or an average can be determined for one or more most recent representations of sensor data from that sensor.
