Abstract
An integrated circuit inductor has a number of vertical metal segments, a number of lower metal straps that electrically connect alternate metal segments, and a number of upper metal straps that electrically connect alternate metal segments to form a continuous electrical path. Layers of a ferromagnetic material are formed normal to the metal segments to extend past at least two sides of each metal segment to increase the inductance of the inductor.
