Název v původním jazyce

Low-power Fluxgate Signal Processing Using Gated Differential Integrator

Popis výsledku v původním jazyce

A novel technique of signal extraction method for pulse excited printed circuit board (PCB) fluxgate sensors is presented. 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. The best results with PCB fluxgate sensor were noise of 20 pT/sqrt Hz@ 1 Hz, linearity error below 70 ppm (in +- 50 uT full scale range), offset stability of 3.7 nT within 3.5 hours.
