For monolithic RF spiral inductor on high-loss silicon substrate, a novel physical model is proposed, in which functions of skin effect, proximity effect and eddy current loss in the substrate to frequency-dependent series parameters Ls and Rs are accounted in the light of modified partial equivalent element circuit methodology and Maxwells electromagnetic theory, and in the meanwhile, the distributed characteristics of parasitic capacitances are captured by n equivalent-circuit. Up to 20GHz, the model reveals quite good accuracy within 7% with data from full-wave electromagnetic filed simulator, including equivalent inductor Leff , resistor Reff and quality factor Q and, hopefully, it can be applied to further theory research and optimum design of RFIC spiral inductor on Si.
