Description

Technical Field

[0001] This case involves inductive devices, particularly differential inductive devices. Background Technology

[0002] Each type of inductor has its advantages and disadvantages. For example, spiral-type inductors have a high quality factor (Q value) and a large mutual inductance. However, their mutual inductance and coupling occur between the coils. For figure-eight inductors, since the magnetic fields induced by the two coils are in opposite directions, their coupling and mutual inductance occur in the coupled magnetic field of the other coil. In addition, figure-eight inductors occupy a larger area in the device. Summary of the Invention

[0003] One aspect of this invention provides an inductor device including a first ring structure and a second ring structure. The second ring structure is disposed within and parallel to the first ring structure. A first open end of the first ring structure is selectively connected to or not connected to a first open end of the second ring structure. Attached Figure Description

Furthermore, the drawings are for illustrative purposes only and are not drawn to their original dimensions. For ease of understanding, the same or similar components will be designated with the same symbols in the following description.

The annular structure 130 is parallel to the annular structure 110. However, this case does not... Figure 1 The annular structures 110 and 130 shown are parallel only. The annular structures 110 and 130 can also be two annular structures with the same or similar shapes. In addition, those skilled in the art can set the structural relationship between the annular structures 110 and 130 according to actual needs.

[0012] The annular structure 110 includes an open end 112, while the annular structure 130 includes an open end 132. The open ends 112 of the annular structure 110 and 132 of the annular structure 130 are selectively connected or not connected.

[0019] like Figure 2 As shown, when both switches 152 and 154 are turned on, the ring structure 110 and the ring structure 130 together form an inductor 210.

[0020] on the other hand, Figure 3 It is illustrated according to some embodiments of this disclosure. Figure 1 Another operational schematic diagram of the inductor 100 is shown. (See diagram below.) Figure 3 As shown, when Figure 1 When both switches 152 and 154 are not conducting, the ring structure 110 forms an inductor 310 on its own.

Figure 2 Inductor 210 and Figure 3 The radii of the inductors 310 are also different. Thus, in this embodiment, different inductance values ​​can be achieved by switching switches 152 and 154.

[0022] Please refer back to Figure 1 In inductor 100, switches 152 and 154 are disposed at the open end 112 of inductor 110 and the open end 132 of inductor 130.

Connector 470 is coupled to the opening end 412 of the annular structure 410 and the opening end 432 of the annular structure 430. Connector 480 is coupled to the opening end 434 of the annular structure 430 and the opening end 414 of the annular structure 410.

One end of switch 484 is coupled to terminal 431D of semi-annular structure 435B, and the other end of switch 484 is coupled to terminal 411D of semi-annular structure 415B.

[0031] In some embodiments, switch 482 is located on one side of intersection 493 (left side in the figure), while switch 484 is located on the other side of intersection 493 (right side in the figure).

[0032] In some embodiments, when both connectors 470 and 480 are on, i.e., when switches 472, 474, 482, and 484 are all on, the ring structures 410 and 430 are connected in parallel to form a common ring structure 910, and the common ring structure 910 and the ring structure 450 form a figure-eight ring structure. On the other hand, when neither connectors 470 nor 480 are on, i.e., when switches 472, 474, 482, and 484 are all off, the ring structures 410 and 450 form a figure-eight ring structure, while the ring structure 430 does not function.

[0033] As described above, by changing the conduction state of connectors 470 and 480, the width, radius, spacing, etc. of the ring structure formed by ring structure 410 and ring structure 430 can be changed, and thus the inductance value of inductor 400 can be changed.

[0034] In some embodiments, such as Figure 4 As shown, the inductor 400 is symmetrical about the axis Y2.

The ring structure 530 is located within the ring structure 510, and the ring structure 550 is located within the ring structure 530. The ring structures 510, 530, and 550 are parallel to each other. However, this application does not... Figure 5 The annular structures 510, 530, and 550 shown are parallel only. The annular structures 510, 530, and 550 can also be annular structures with the same or similar shapes. In addition, those skilled in the art can set the structural relationship between the annular structures 510, 530, and 550 according to actual needs.

[0036] In some embodiments, the annular structure 510 further includes semi-annular structures 515A and 515B.

[0044] In some embodiments, when connector 580 is on, i.e., when switches 582 and 584 are on, ring structures 530 and 550 are connected in parallel to form a common ring structure 920, and the common ring structure 920 and ring structure 510 form a figure-eight ring structure. On the other hand, when connector 580 is not on, i.e., when switches 582 and 584 are not on, ring structures 510 and 530 form a figure-eight ring structure, while ring structure 550 does not function.

[0045] As described above, by changing the conduction state of connector 580, the width, radius, spacing, etc. of the ring structure formed by ring structure 530 and ring structure 550 can be changed, and thus the inductance value of inductor 500 can be changed.

[0046] In some embodiments, such as Figure 5 As shown, the inductor 500 is symmetrical about the axis Y3.

[0047] The number, connection method, and position of the switches illustrated in the above embodiments are for illustrative purposes only, and the embodiments in this case are not limited thereto.

[0049] It should be noted that in the implementation of this case, switches 152, 154, 482, 484, 472, 474, 582, and 584 can be controlled together, or they can be separate single-link devices that can be controlled independently, depending on the actual needs.

[0050] The inductor in this embodiment can change the width, radius, and spacing of the ring structures formed between multiple ring structures by changing the on state of the switch, thereby changing the inductance value of the inductor. At the same time, the Q (quality) value of the inductor can be maintained.
