ABSTRACT:
A transformer includes a flex or printed circuit board consisting of a substrate material having a desired permittivity, and at least one primary winding and at least one secondary winding. Each winding is integrated with the flex or printed circuit board such that one or more respective transformer parasitic elements and the substrate permittivity between the primary and secondary windings together are tuned to a desired parallel resonant frequency.
