碩士 === 國立成功大學 === 電腦與通信工程研究所 === 104 === This thesis presents the research on CMOS millimeter-wave (MMW) medium power amplifiers (PAs) and a 94-GHz CMOS sub-harmonic single-mixer RF transceiver (TRx), implemented by standard TSMC 90-nm GUTM CMOS process. In the 94-GHz CMOS medium power amplifier (MPA) design, a four stage class-A common-source (CS) cascode structure with gain-boosting technique is adopted for linearity and power gain enhancement. In the 94-GHz CMOS balanced PA design, a compact 3-dB miniaturized quadrature coupler is employed as a low-insertion-loss power splitter/combiner to improve the output power and provide an area-efficient solution for balance PA design. In the 94-GHz CMOS single-mixer TRx, a high-gain PA is designed for integrating with T/R switches, a low-noise amplifier (LNA), and a sub-harmonic single up/down conversion mixer. The CMOS TRx uses only one up/down conversion mixer and T/R switches to change the modes between transmitting (Tx) and receiving (Rx) path. Compared with the traditional TRx architecture, it can reduce the chip size without the use of additional mixer and filters, and also simplify the complexity of TRx design. The measured performances of the designed MMW CMOS RFICs are all performed by using the on-wafer measurement. Simulation and measurement results are compared and discussed.
