ABSTRACT:
Methods and systems are provided for reducing circuit area. Some embodiments provide electronic devices including an inductor formed from a path having two ends that loops substantially in a plane around a center area, wherein the path crosses itself at least two points and wherein the path defines an outer boundary of the inductor; and a circuit that is located within the outer boundary of the inductor and substantially within or adjacent to the plane. Other embodiments provide electronic devices including an inductor formed from a path having two ends that loops substantially in a plane around a center area, wherein the path defines an outer boundary of the inductor; and a circuit that is located within the outer boundary of the inductor and substantially within or adjacent to the plane, and wherein the circuit comprises a signal path that is rake-shaped and crosses the path of the inductor at substantially perpendicular angles.
