Abstract
Performance of magnetic thin-film is evaluated as a candidate for on-chip inductive intra noise decouplor. Miniature loop coils implemented on a 90 nm design CMOS test element group (TEG) chip are used as the noise transmitter and receiver. Differential transmission parameter $S-{{\rm dd}21}$ is evaluated as the measure of intra-decoupling. Magnetic film is useful for frequency selective noise decouplor. The coupling is supported most at the ferromagnetic resonance (FMR) frequency, which is deviated from its intrinsic frequency and the degree of deviation can be calculated by using characteristic length. These results demonstrate that the proposed method is useful to characterize the IC chip level noise suppressor in the GHz range.
