Abstract: An equivalent circuit for a novel RF integrated inductor with ferrite thin-film is derived.The enhancement of the magnetic ferrite thin-film on the inductance (L) and quality factor (Q) of the inductor is analyzed.Circuit element parameters are extracted from RF measurements.Compared with the reference air-core inductor without magnetic film,L and Q of the ferrite thin-film inductor are 17% and 40% higher at 2GHz,respectively.Both the equivalent circuit analysis and test results demonstrate significant enhancement of the performance of RF integration inductors by ferrite thin-film integration.

Key words: inductor equivalent circuit ferrite thin-film RF ICs
