Abstract
Disclosed is a resonant magnetic field sensor, comprising a detector structure including a mass block and displacement detection electrodes; capacitance to voltage converter and amplifier to convert detection signals of the detection electrodes into voltage signals, as output signals of the magnetic field sensor; and a vibration driving circuit to provide the output signals to the mass block in the form of a current, to drive the mass block to vibrate. The vibration driving circuit may be a comparator.
