Ferrite Magnetic-Anisotropy Field Effects on Inductance and Quality Factor of Planar GHZ Inductors

Abstract: Abstract-Planar gigahertz (GHz) inductors were fabricated based on high crystalline-anisotropy Zn 0.13 Co 0.04 Ni 0.63 Fe 2.2 O 4 (Zn-Co-Ni ferrite) and Ba 3 Co 2 Fe 24 O 41 (Co 2 Z hexaferrite) and characterized for inductance (L) and quality (Q) factor. The planar ferrite inductors show an L of 4.5 nH (Zn-Co-Ni), 5.6 nH (Zn-Co-Ni + low H k and f FMR Co 2 Z:), and 4.8 nH (Zn-Co-Ni + high H k and f FMR Co 2 Z:) at 2 GHz. The corresponding L-densities are 18.0, 22.4, and 19.2 nH/mm 2 , which are greater than 16… Show more
