Abstract
Description
Technical Field
[0001] The present application relates to a device, and in particular to an inductive device. Background Art
[0002] Various existing inductors have their advantages and disadvantages. For example, a spiral-type inductor has a higher quality factor (Q value) and a larger mutual inductance. However, its mutual inductance and coupling occur between the coils. For a figure-eight inductor, since the induced magnetic fields of its two coils are in opposite directions, its coupling and mutual inductance occur in the coupled magnetic field of the other coil. In addition, the figure-eight inductor occupies a larger area in the device.
[0003] Therefore, it is desirable to provide an inductor device to provide different inductance values so as to expand the application range of the inductor device and maintain the quality factor of the inductor. Summary of the invention
[0004] One aspect of the present application is to provide an inductive device, comprising a first ring structure, a second ring structure and a third ring structure. The second ring structure is coupled to the first ring structure and forms an eight-shaped loop with the first ring structure. The third ring structure is coupled to the second ring structure, wherein the first ring structure and the second ring structure are located in an area surrounded by the third ring structure.
