Application Notes
Noise In NVE Giant Magnetoresistive Sensors
The 1/f noise characteristic of NVE GMR sensors is approximately an order of magnitude higher than
noise for thin film resistors. The noise has been shown to follow the usual characteristics of being
proportional to the square of the current density. The figure below shows a noise plot of an AA002-02
sensor using various methods for powering the sensor:

Log Frequency (Hz)
For use in low-field applications, the noise of the NVE GMR sensors limits the minimum signal
detected. For measuring low fields it is recommended that an AC modulation/demodulation scheme be
implemented. The figure below shows a block diagram of an AC modulation/demodulation circuit.
The phase shifter block is required to account for parasitic phase shift around the loop.
