Abstract
A high performance, on-chip a parallel stacked inductor which achieves a higher Q value. The inductor is formed on a layered substrate with a top metal layer having spiral winding conductive segments that terminate at an overpass junction, and a bottom metal layer traversing adjacent to, and parallel with, the top metal layer. The bottom metal layer having multiple bar vias imbedded therein for current carrying capabilities. The overpass junction having a width that is greater than the width of the adjacent spiral winding conductive segments.
