Abstract
Systems and techniques for a detecting a magnetic target that reduce output signal jitter are disclosed. A system includes a magnetic target. The magnetic target has a plurality of regions having juxtaposed edges and opposing ends. Adjacent ones of the plurality of regions have different magnetic polarities. The magnetic target includes a first magnetic strip, having a first magnetic polarity disposed at one end of the regions, and a second magnetic strip having a second magnetic polarity opposite to the first magnetic polarity disposed at a second end of the regions to generate a magnetic bias across at least a portion of the regions. The system includes at least one magnetic field sensing element placed in proximity to the magnetic target and configured to produce an output signal responsive to the magnetic target.
