Systems and methods for high precision feedback control in closed loop sensors

摘要

Improved methods and systems for feedback signals in a sensor system. An example method demodulates a sense signal using an analog demodulator (60) and also demodulates the sense signal using a digital demodulator (64). The difference between the result of the analog demodulator and the digital demodulator is determined (50) and then integrated (52). A sensor feedback control signal is generated (54) based on the integrated difference.
