Abstract: Sensor error detection with an additional sensing channel is disclosed herein. First, second, third sensing elements can be disposed at angles relative to one another. In some embodiments, the first, second, and third sensing elements can be magnetic sensing elements, such as anisotropic magnetoresistance (AMR) sensing elements. Sensor data from first, second, and third sensing channels, respectively having the first, second, and third sensing elements, can be obtained. Expected third sensing channel data can be determined and compared to the obtained third sensing channel data to indicate error.

In some embodiments, the first and second magnetic sensing elements can be magnetoresistive sensing elements, such as anisotropic magnetoresistance (AMR) sensing elements. Sensor data from first and second channels, respectively, having the first and second sensing elements, can be obtained. Third channel can receive a signal from the first sensing element and a signal from the second sensing element, and sensor data from the third channel can be obtained. Expected third channel data can be determined and compared to the obtained third channel data to indicate error.
