Application Notes
This biasing technique creates a bipolar output with a DC offset. Another typical purpose for this kind
of biasing is to bias the sensor away from the zero field area, where hysteresis is more pronounced.
Since gradiometers respond to the flux gradient rather than the field itself, they can be biased to zero
offset to work in a gear tooth sensing application. It is important not to bias a gradiometer to a high
enough field to saturate the GMR resistors.
More information on biasing gradiometers for gear tooth sensor applications is found in the GT Sensor
application notes section.
