Abstract
Integrated high frequency balanced-to-unbalanced transformers and inductors suitable for operation in high frequencies, such as radio frequencies. Embodiments disclosed give consideration to issues related to the layout of the top and bottom inductors for the minimization of capacitive effects between layers and methods of manufacturing thereof. The manufacturing process comprises forming of a first winding in a first metal layer; forming an insulating layer over at least the first metal layer; forming of a second winding in a second metal layer such that the second winding path has both a vertical and a horizontal displacement to the first conductive path, preferably with an overlap that is less than a full overlap; and forming shunts to ensure continuity of each of the first and second windings.
