Abstract
Methods and systems for detecting a rotating target are disclosed herein, wherein a biasing magnet is associated with a rotating target in association with a dual peak detector. The rotating target generally comprises a plurality of teeth and at least one slot formed between at least one tooth of the rotating target. In general, the biasing magnet and the rotating target generate a magnetic signal having positive and negative peaks thereof. The dual peak detector includes a tooth detector and a slot detector, such that the dual peak detector detects a minimum and maximum peak of the magnetic signal generated by the biasing magnet and the rotating target. Additionally, a clamping circuit can be associated with the dual peak detector, wherein the clamping circuit can provide a true power on (TPO) functionality.
