Systems and methods having omnipolar comparators for magnetic switches

An omnipolar magnetic sensor system comprising:

• a magnetic sensor configured to measure a magnetic field and to generate a sensor signal having an amplitude and a polarity;
• a comparator configured to receive the sensor signal, to generate a balanced signal from the sensor signal using behavior parameters, to selectively chop the balanced signal to generate a chopped balanced signal, and to generate a digital output based on omnipolar behavior and the chopped balanced signal, wherein the comparator utilizes the behavior parameters and chops the balanced signal on the digital output being at a predefined value;
• and
• a behavior component configured to generate the behavior parameters and a signal used to chop or toggle the balanced signal according to at least the digital output, wherein the behavior parameters include a hysteresis signal and an offset signal, wherein the behavior component includes a hysteresis signal generator configured to generate the hysteresis signal using one or more hysteresis switches configured to toggle output of the hysteresis signal based on an intermediary signal and an offset signal generator configured to generate the offset signal using one or more offset switches configured to toggle output of the offset signal based on the intermediary signal.
