Abstract
An on-chip inductor structure includes first and second winding portions symmetrically arranged in an insulating layer by a symmetrical axis. Each of the first and second winding portions includes first and second semi-circular conductive lines concentrically arranged from the inside to the outside. First and second input/output conductive portions are disposed in the insulating layer along the extending direction of the symmetrical axis, to respectively and electrically couple the first ends of the outermost semi-circular conductive lines. A conductive branch structure is disposed in the insulating layer along the symmetrical axis and between the first and second input/output conductive portions, and electrically coupled to first ends of the innermost semi-circular conductive lines. The conductive branch structure has a grounded first end and a second end is electrically coupled to a circuit and is opposite the first end of the conductive branch structure.
