| Abstract(in English) | A long term evolution (LTE)-class CMOS radio frequency integrated circuit (RFIC) receiver test element group (TEG) chip is developed in our project for the next generation cell phone handsets in order to clarify the on-chip-level noise coupling and demonstrate the noise attenuation using the soft magnetic thin film as an on-chip electromagnetic noise suppressor. The TEG chip equips a noise generator and a RF receiver block. The RF block amplifies and demodulates transmitted signals to IQ signals. A Co_<85>Zr_3Nb_<12> soft magnetic thin film is integrated onto the TEG chip as a noise suppressor. In this report. the noise generator is driven by a clock signal of 1 24.803 MHz and generates 17th harmonics of 2,165MHz conflicts with the LTE band 1 (2,110-2,170MHz). As a result. the in-band digital noise was suppressed 5-20dB by the Co-Zr-Nb thin film as an integrated noise suppressor. |
