1. A sensor circuit comprising:
a comparator connected to a first terminal of a winding;
a passive circuit comprising a resistor and a capacitor, wherein the resistor and capacitor are connected in series, wherein the passive circuit is connected, at a first end, to a first input of the comparator and, at a second end, to a fixed potential;
a feedback loop connected to a second terminal of the winding and the first input of the comparator; and
a hysteresis unit connected to a second input of the comparator.
