Abstract

The invention discloses a transformer structure including a first inductor and a second inductor. The first inductor has a first turn and a second turn. The second inductor has a third turn and a fourth turn. The first turn of the first inductor and the third turn of the second inductor are disposed in a first region of a first metal layer. The second turn of the first inductor and the fourth turnof the second inductor are disposed in a second region of the first metal layer. The first region is adjacent to the second region.

Description

technical field [0001] The present disclosure relates to an inductor structure. More specifically, the present disclosure relates to a transformer structure. Background technique [0002] Today, inductor devices and transformer structures formed from inductors are essential in integrated circuits. However, achieving a satisfactorily higher inductance usually results in a lower coupling coefficient and quality factor. Therefore, improvements to these transformer structures are needed. Contents of the invention [0003] The present invention provides a transformer structure with a good quality factor (Q value). [0004] The present disclosure relates to a transformer structure. The transformer structure includes a first inductor and a second inductor. The first inductor has first and second turns. The second inductor has third and fourth turns. The first turn of the first inductor and the third turn of the second inductor are arranged mutually in the first region of t...
