METHOD FOR MEASURING A WEAK MAGNETIC FIELD AND MAGNETIC FIELD SENSOR HAVING AN IMPROVED SENSITIVITY
摘要
<p>A magnetic field sensor comprises a magnetoresistive element (10) that is current polarized (i) for measuring an external magnetic field (H<SUB>ext</SUB>). A modulation magnetic field (H<SUB>m</SUB>) is applied to a sensitive region of said sensor, and the sensor comprises a synchronous detection device (14) for measuring the amplitude of an odd harmonic of the output signal.</p>
