Characterization of CMOS Metamaterial Transmission Line by Compact Fractional-Order Equivalent Circuit Model.

In this paper, a compact fractional-order equivalent circuit model is developed to characterize three types of metamaterial transmission lines (T-lines): 1) composite right-/left-handed transmission line T-line; 2) split ring resonator T-line; and 3) complimentary split ring resonator T-line, all designed in 65-nm CMOS process at millimeter-wave frequency region. With the consideration of frequency-dependent dispersion loss and nonquasistatic effect, the proposed fractional-order equivalent circuit model can compactly characterize the measured results with good agreement up to 325 GHz.
