The signal extraction electronics takes an advantage of the sensor output voltage waveform shape with bipolar consecutive pulses with polarity and amplitude corresponding to the measured field and utilizes two gated integrators active only in the presence of the sensor output pulses. The feedback loop operation has also been implemented and successfully verified for PCB fluxgate sensors. The results indicate a significant improvement in the noise of pulse-excited sensors when compared to classical 2nd harmonic detection of signal from these pulse excited sensors.
