Abstract
Transmission lines employing transmission line units or elements within integrated circuits (ICs) are well-known. Typically, different heights for these transmission line units can vary the characteristics of the cell (and transmission line), and there is typically a tradeoff between impedance and space (layout) specifications. Here, a transmission line is provided, which is generally comprised of elements of the same general width, but having differing or tapered heights that allow for impedance adjustments for high frequency applications (i.e., 160 GHz). For example, a transmission line that is coupled to a balun, with the transmission line units decreasing in height near the balun's center tap to adjust the impedance of the transmission line for the balun, is shown.
