Sensor and method of operation of the same including noise compensation

摘要

An apparatus includes a sense element and an oscillator. The oscillator is coupled to the sense element and is used to generate an oscillator signal and a gain control signal. The oscillator signal is amplitude compensated when noise is detected in the sense element. A method includes detecting magnetic interference in a sense element coupled to an oscillator, and adjusting a gain control signal in the oscillator to compensate for the magnetic interference.
