Abstract
An apparatus is provided that includes an inductor, a pair of modulating coils, a first switch and a second switch. The inductor includes two sub-loops electrically coupled with each other. The modulating coils include a first modulating coil and a second modulating coil respectively disposed corresponding to each of the two sub-loops. The first switch and the second switch are respectively disposed at the first modulating coil and the second modulating coil. Each of the first modulating coil and the second modulating coil forms an open loop when the first switch and the second switch are under an open status, and each of the first modulating coil and the second modulating coil forms a closed loop when the first switch and the second switch are under a closed status that enables a modulation of an inductance of the inductor.
