Abstract

We report new high quality factor (Q) integrated GHz magnetic inductors based on solenoid structures with FeGaB/ {\rm Al}-{2}{\rm O}-{3} multilayer films, which show significantly enhanced inductance and quality factor at GHz frequencies over their air core counterparts. These inductors show an excellent high-frequency performance with a wide operation frequency range 0.5-2.5 GHz, in which the inductance is flat and the peak quality factor can reach {\sim}{\rm 20}. The inductance of the magnetic inductor shows {>}{100\%} enhancement compared with that of the same size air core inductor. These novel GHz inductors with high inductance and Q enhancement show great promise for applications in radio frequency integrated circuits.
