ABSTRACT:
A driver circuit for a fluxgate magnetometer has a repetition rate controble independent of the magnetometer core winding inductances, and a current-ON interval terminated only by core saturation. In this manner, power consumption is greatly reduced as compared to prior magnetometers without sacrificing low-noise operation. Previous drivers operated in a free-running flyback mode at high pulse repetition rates. The present driver reduces the oscillator repetition rate, and power consumption, by the use of a control loop from the flyback oscillator which signals the end of a current pulse as the magnetometer core rebounds from the saturated state.
