Noise coupling path on a fully LTE-compatible receiver circuit chain (Band1, 2110-2170 MHz for downlink) has been analyzed to estimate the victim wires that carry digital noise from RF digital to analogue circuits on the test RF IC chip, three noise-carrying wire groups were extracted out of numerous on-chip wires through systematic measurements and electromagnetic simulation. Then the patterned amorphous Co-Zr-Nb film was integrated only along the extracted wire groups on the test chip. Measured noise level and LTE throughput performance clarified lower in-band spurious tone (noise) by 9.3 dB as compared with the non-magnetic original chip, and also better than non-patterned magnetic film by 7.3 dB. These results and EM simulation made sure the noise coupling path on chip, and suggesting the noise diffusion in the original larger film blocks.
