Abstract
Integrated high frequency balanced-to-unbalanced transformers suitable for operation in high frequencies, such as radio frequencies. Embodiments disclosed give consideration to issues related to the layout of the primary and secondary inductors for the minimization of capacitive effects between layers while using a minimal number of metal layers. Two solutions are provided, one having embodiments with a symmetrical primary inductor in a 4-metal layer implementation and one having embodiments with a non-symmetrical primary inductor in a 3-metal layer implementation.
