Abstract
Transformers that provide impedance transformations within integrated circuits (ICs) are disclosed. Embodiments of the transformers may include a plurality of conductors connected in series within one another wherein the conductors are arranged to form transmission lines. A first port, a second port, and a third port are coupled to the conductors so that impedance transformations can be provided between the first port and the second port. Some embodiments of the transformers are arranged so that the third port can be used to apply a bias signal. The arrangement between the conductors and the ports allows the transformer to provide impedance transformations between the first port and the second port over a relatively wide passband at high frequency ranges and with relatively small insertion losses.
