Compact Modeling of Spiral Inductors for RF Applications


Keywords: , ,

Recent growth in RF applications has increased the use of spiral inductors and thus demanded a more accurate model for such devices. In this paper, we develop a compact model for spiral inductors with symmetrical and asymmetrical terminals. Relevant and important physics such as the current crowding in metal line, coupling capacitance, frequency-dependent permittivity in oxide, and overlap parasitics are accounted for. Experimental data and results calculated from the existing inductor models are included in support of the model development.
