Abstract:
A transmission line element formed in an integrated circuit chip comprising:a plurality of metal layers, each of said metal layers being separated from an adjacent said metal layer by at least one dielectric layer; a first conductor comprising at least two transmission lines in different said metal layers; a second conductor comprising at least two transmission lines in different said metal layers, the transmission lines in said first and second conductors running parallel to each other; a plurality of interconnects located at predetermined positions along said conductors, each of said interconnects containing an electrical connection between the transmission lines in said first conductor and an electrical connection between the transmission lines in said second conductor; wherein at least one transmission line in said first conductor is edge-coupled to at least one transmission line in said second conductor and broadside-coupled to at least one other transmission line in said second conductor.
