Embodiments of the present invention pertain to windings and methods thereof. A disclosed winding is for an inductive device, having a winding core and a winding portion. The winding portion has a first winding layer, a connection section, and a second winding layer. The first winding layer comprises a first solenoid wound around the winding core along a step direction. The connection section is on the first winding layer, substantially in parallel to the step direction. The second winding layer comprises a second solenoid wound around the first winding layer along the step direction. The connection section electrically connects the first and second winding layers.
