1. An inductor device, comprising:
a first trace disposed in a first area, and located on a first layer;
a second trace disposed in the first area, coupled to the first trace, and located on a second layer;
a third trace disposed in a second area, and located on the first layer;
a fourth trace disposed in the second area, coupled to the third trace, and located on the second layer; and
a double ring inductor disposed on the first layer, located at an outside of the first trace and the third trace, and coupled to the first trace and the third trace, wherein the double ring inductor comprises:
a fifth trace disposed in the first area, and coupled to the first trace;
a sixth trace disposed in the second area, and coupled to the third trace;
a first connector coupled to the fifth trace and the sixth trace at a first side of the inductor device; and
a second connector coupled to the fifth trace and the sixth trace at a second side of the inductor device;
wherein the second trace comprises at least one wire, and the second trace and the fifth trace are partially overlapped with each other at the first side and the second side.
