Year: 2013
Type: article
Abstract: Several kinds of ferrite‐integrated on‐chip inductors are presented. Ferrite nanomaterial applied in RF on‐chip inductors is prepared and analyzed to show the properties of high permeability, high ferromagnetic resonance frequency, high resistivity, and low loss, which has the potential that will improve the performance of RF on‐chip inductors. Simulations of different coil and ferrite nanomaterial parameters, inductor structures, and surrounding structures are also conducted to achieve the trend of gains of inductance and quality factor of on‐chip inductors. By integrating the prepared ferrite magnetic nanomaterial to the on‐chip inductors with different structures, the measurement performances show an obvious improvement even in GHz frequency range. In addition, the studies of CMOS compatible process to integrate the nanomaterial promote the widespread application of magnetic nanomaterial in RF on‐chip inductors.
