Abstract
Sensor circuitry utilizing feedback to balance sensor output data is provided. An apparatus can include a primary coil and a first secondary coil outputting a first voltage. The apparatus can also include a second secondary coil outputting a second voltage. The apparatus can further include circuitry coupled to the first secondary coil and the second secondary coil. The circuitry can be configured to receive the first voltage from the first secondary coil and the second voltage from the second secondary coil. The circuitry can also be configured to determine a feedback voltage based on a difference between the first voltage and the second voltage. The feedback voltage can correct the difference. The circuitry can also modify a third voltage that can be output by the circuitry to be zero based on the feedback voltage.
