Abstract
A magnetic sensor bearing utilizes an adaptive threshold circuit for signal processing in order to compensate for external factors such as temperature, stress, aging, and external magnetic fields which all affect a fixed reference signal used with a comparator. As the magnetic sensor's output signal drifts due to these external factors, the adaptive threshold circuit causes the reference signals to drift in a complementary manner so that the magnetic sensor bearing continues to function properly in spite of the external factors.
