Low-noise fluxgate magnetometer with increased operating temperature range
A magnetic field measurement device includes an excitation circuit including an excitation coil that is coupled to a resonation control circuit. The excitation coil is wound around an amorphous soft magnetic core. The magnetic field measurement device includes a detection circuit including a detection coil that is wound around the amorphous soft magnetic core. The resonation control circuit is coupled to the excitation circuit and to the detection circuit to adjust a resonant frequency of the detection circuit responsive to temperature variations of the amorphous soft magnetic core.
