摘要：
Fluxgate magnetometers are preferred in a number of applications because of their higher sensitivity, low noise level, robustness, and thermal and long-term stability. Currently, a new way to operate fluxgate magnetometers is represented by the residence times difference (RTD) fluxgate. The scheme is based on a two-coil structure wound around a suitable magnetic core having a hysteretic input-output characteristic.
