1. An apparatus comprising:
a first terminal and a second terminal;
a first circuit comprising a first inductor connected in parallel to a capacitor and connected in parallel to a resistor;
a second circuit comprising a second inductor, wherein the second inductor has a higher inductance and a lower saturation current than the first inductor, and wherein the first circuit and the second circuit are connected in series between the first terminal and the second terminal to form a current path between the first terminal and the second terminal;
a first sensor configured to sense a level of current in the current path;
a second sensor; and
a controller configured to determine, based on one or more measurements of the second sensor, a value corresponding to one of: a resonant frequency of the first circuit, a quality (Q) factor of a resonance corresponding to the resonant frequency, a resistance of the resistor, an impedance of the first circuit, or a bandwidth of the apparatus.
