Abstract
A high frequency planar inductor fabricated directly on ferrite substrate is proposed in this paper. The NiCuZu ferrite was selected as the substrate. Due to NiCuZn´s high resistivity, no insulator is required. So, it is an advantage in terms of ease fabricated and stray capacitance reduction. Sandwiched inductors show improvement of inductance from 16nH to 80nH at 1MHz compare with the coreless inductors, and the increment of inductance is larger than the magnetic thin-film inductor.
