Abstract: An inductor module comprising: a first inductor, comprising a first inductor area; and a second inductor, comprising a second inductor area. A first overlapped area of the first inductor area and a second overlapped area of the second inductor area are overlapped. The second overlapped area comprises at least one first magnetic direction area and at least one second magnetic direction area. A ratio between a size of the first magnetic direction area and a size of the second magnetic direction area is a predetermined ratio such that a coupling effect between the first inductor and the second inductor is lower or equals to a predetermined value.

Abstract: A composite inductor structure is provided, which comprises: a first spiral inductor and a second spiral inductor. The first spiral inductor has a plurality of loops and generates a first electromagnetic field, wherein an outermost loop of the first spiral inductor has a first end point, and an innermost loop of the first spiral inductor has a second end point. The second spiral inductor is arranged to be adjacent to the first spiral inductor, and has a plurality of loops and generates a second electromagnetic field, wherein an outermost loop of the second spiral inductor has a third end point, and an innermost loop of the second spiral inductor has a fourth end point, and the second spiral inductor is rotated by a specific degree with respect to an orientation of the first spiral inductor, and the first electromagnetic field and the second electromagnetic field are oppositely directed.
