Zusammenfassung:This contribution presents, in a reverse engineering like approach, the noise measurements and analysis of two commercially available magneto-resistive currents sensors respectively based on GMR (NVE Inc.) and AMR (SENSITEC GmbH) Wheatstone bridges. Comparison is done with the ultimate aim of designing low noise current conditioners for mini search coils based, magnetometers with galvanic insulation useful for further developments.
