Abstract

This paper presents a physically meaningful equivalent circuit of the ferromagnetic RF integrated inductor, valid over a wide frequency range: DC to 20 GHz. CoNBZr ferromagnetic film was micro-patterned on top of the inductors to enhance inductance and quality factor. Multi-objective Nelder-Mead simplex method was used to optimize the complex equivalent circuit parameters. The frequency profile of the ferromagnetic RF integrated inductor is presented.
