1. An inductor device, comprising:
a first ring-type structure;
a second ring-type structure, coupled to the first ring-type structure and formed an 8-shaped loop with the first ring-type structure;
a third ring-type structure, coupled to the second ring-type structure, wherein the first ring-type structure and the second ring-type structure are located at an area surrounded by the third ring-type structure; and
a first connector, coupled to the second ring-type structure and the third ring-type structure, wherein the first connector includes a first mode and a second mode,
wherein in response to that the first connector is conducted, a first current flows from a first terminal of the third ring-type structure directly to a second terminal of the third ring-type structure, and a second current flows from a first terminal of the second ring-type structure directly to a second terminal of the second ring-type structure,
wherein in response to that the first connector is not conducted, the first current flows from the first terminal of the third ring-type structure to the first terminal of the second ring-type structure, and flows from the second terminal of the second ring-type structure to the second terminal of the third ring structure.
