Abstract
In some implementations, a magnetic sensor may apply an electrical signal across a tunnel barrier layer of a tunnel magnetoresistive (TMR) sensing element. The electrical signal may have a first signal level during a first time period and a second signal level during a second time period. The second signal level may be different from the first signal level. The magnetic sensor may generate an offset-corrected sensor signal based on a sensor signal that results from applying the electrical signal across the tunnel barrier layer of the TMR sensing element.
