High q factor inductor structure

Structure d'inducteur à facteur de surtension élevé

Abstract

The present disclosure provides a vertical inductor structure in which the magnetic field is closed such that the magnetic field of the vertical inductor structure is cancelled in the design direction outside the vertical inductor structure, yielding a small, or substantially zero, coupling factor of the vertical inductor structure. In one embodiment, several vertical inductor structures of the present disclosure can be placed in close proximity to create small resonant circuits and filter chains.
La présente invention concerne une structure d'inducteur verticale pour laquelle le champ magnétique est fermé de sorte que le champ magnétique de la structure d'inducteur verticale est annulé dans la direction de conception en dehors de la structure d'inducteur verticale, ce qui génère un facteur de couplage faible, ou sensiblement nul, de la structure d'inducteur verticale. Selon un mode de réalisation, plusieurs structures d'inducteur verticales selon la présente invention peuvent être placées à proximité immédiate pour créer de petits circuits résonants et de petites chaînes de filtre.
