【 英文摘要 】The invention discloses an adjustable three-dimensional inductor with a compact structure. Comprising a silicon substrate layer, An upper surface of the silicon substrate layer is provided with a top dielectric layer, The lower surface of the silicon substrate layer is provided with a bottom dielectric layer, Two annular magnetic cores are concentrically arranged in the top dielectric layer and the bottom dielectric layer, A first spiral inductor is wound around the outer magnetic core of the top dielectric layer and the outer magnetic core of the bottom dielectric layer. A second spiral inductor separated from the first spiral inductor is wound outside the magnetic core close to the inner part of the top dielectric layer and the magnetic core close to the inner part of the bottom dielectric layer together, and one end close to the inner part of the first spiral inductor is connected with one end close to the outer part of the second spiral inductor through a metal strip positioned in the top dielectric layer or the bottom dielectric layer. The invention relates to an adjustable three-dimensional inductor with a compact structure, which solves the problem of large occupied area of the conventional inductor.
