ABSTRACT:
An integrated circuit (IC) includes one or more inductors that have magnetic flux lines substantially parallel to a generally horizontal plane of the IC. The inductor is formed in a plurality of conductor layers separated by insulating layers of the IC. Regions of highest magnetic flux density of the inductor may preferably be located near the edge of the IC. Additionally, the inductor may preferably be segmented. The over-all inductance may preferably be controlled by turning on and off selected inductors or inductor segments.
