Two conducting wires are used in one embodiment of an inductor. Opposite ends of each of the conducting wires are connected to leader lines (terminals) shared by the conducting wires. Each of the conducting wires is wound to make half a round of an annular or ring-like magnetic substance. One of the conducting wires is wound around a lower half area of the magnetic substance to form one winding while the other conducting wire is wound around an upper half area of the magnetic substance to form another winding. In this manner, the distance between the leader lines can be increased to eliminate parasitic capacitance between the leader lines. The magnetic fluxes generated by current flowing in the two windings are in the same direction. Thus, it is possible to provide an inductor whose total parasitic capacitance is reduced. In other embodiments, additional conducting wires are used. |
