| Research Abstract |
In this work, a fundamental theory of scalable RF transceiver has been studies for realizing 1Tbps ultra-high-speed wireless communication. The key technology for the scalable RF transceiver is the improvement of gain, linearity and noise characteristics, and a circuit technique to maintain the circuit performance even with the process fluctuation. In this work, the proposed digital RF technique is applied to realize a self-calibration of the60GHz wireless transceiver implemented by 65nm CMOS. The phase noise degradation is avoided by using the proposed injection-locked oscillator, which results in a 20-dB improvement in the phase noise. Finally, a 20Gbps wireless transceiver has been realized, which is the fastest among wireless transceiver ICs.
