Low-loss planar inductor

Abstract

The invention discloses a low-loss planar inductor. The inductor comprises an inductor body and a framework for fixing the inductor body, the framework comprises a base and a placing body which is integrally formed with the base; one side of the placement body is open, a cover body is hinged to the top of the placing body, rectangular holes are formed in the two sides of the placing body and communicated with the cover body, an electrode column extends from the bottom of the inductor body and extends from the rectangular holes, the top of the base and the bottom of the placing body are on thesame plane, and pin outlets are formed in the electrode column and used for pins of the inductor body to penetrate through. Compared with the prior art, the inductor has the advantages that the framework is used for placing the inductor body in the placing body, the framework is used for being placed on a circuit board, the planar inductor body in the placing body can be replaced when the inductoris damaged, and due to the fact that the rectangular holes and the rectangular through holes are formed in the framework, the heat dissipation effect can be improved, and losses can be reduced.

Description

technical field [0001] The invention belongs to the field of semiconductors, and in particular relates to a low-loss planar inductor. Background technique [0002] In the development of CMOS radio frequency integrated circuits (RFIC), the most urgent and difficult thing is to develop high-performance new devices and new unit circuits, which are the basis for realizing monolithic CMOS integrated RF front-end. As a key component in radio frequency integrated circuits, planar inductors are the most difficult components to design and master in circuits, and their performance parameters directly affect the performance of radio frequency integrated circuits. On-chip inductors enable the integration of inductors in radio frequency integrated circuits. [0003] Most of the on-chip planar inductors are wound on a silicon substrate through a metal film. Compared with traditional wire-wound inductors, on-chip planar inductors have the advantages of low cost, easy integration, low nois...

AI Technical Summary

Problems solved by technology

[0004] The existing inductor is a consumable in the circuit. Once the inductor is damaged, the entire circuit board will be unusable. Therefore, it is very important to obtain a low-loss planar inductor that is easy to replace.
