An on-chip inductor can include an outer inductor portion that separates an inner region of the inductor from an outer region of the inductor outside the inductor. An interconnect inductor portion is electrically coupled to the main inductor portion wherein the interconnect inductor portion can include extension portions that follow the contour of the adjacent portions of the outer inductor in the inner region of the inductor. An input path is coupled to the outer inductor portion through the extension portion and extends away from the inductor beneath the outer inductor portion on a first side thereof. An output path is coupled to the outer inductor portion through the extension portion and extends away from the inductor beneath the outer inductor portion on a second side of the inductor opposite the first side.
