本論文提出三個電路的設計和製作，包含兩個利用互補式簡化型交連耦合設計的壓控振盪器和一個自振式混波器。電路皆以TSMC 0.18 μm 1P6M CMOS製程來製作。
操作頻率在15 GHz的Ku band壓控振盪器具有大約–4 dBm的輸出功率，實際量測到的相位雜訊在偏移中心頻率1 MHz 時為–103.11 dBc/Hz。Ku band壓控振盪器的FOM是–178.2 dBc/Hz。雙頻帶壓控振盪器在工作偏壓為1.5 V時，偏壓電流為2 mA。實際量測相位雜訊在2.14 GHz偏移中心頻率1 MHz 時為–117.94 dBc/Hz，在4.5 GHz偏移中心頻率1 MHz 時為–111.09 dBc/Hz。雙頻帶壓控振盪器的FOM分別為–179.8和–179.4 dBc/Hz。自振式混波器在RF輸入頻率為9.2 GHz時大約有6 dB的轉換增益。實際量測電路的LO相位雜訊在6.84 GHz偏移中心頻率1 MHz時為–135.6 dBc/Hz，FOM為–198.609 dBc/Hz。

This thesis proposes three circuits and they are designed, implemented, and measured. These circuits include two complementary simplified cross–coupled VCOs and a self–oscillating mixer fabricated in TSMC 0.18 μm 1P6M CMOS process.
The Ku–band oscillator at the center frequency of 15 GHz associated with about –5 dBm output power. Measured phase noise is –103.11 dBc/Hz at 1 MHz offset. The Ku–band VCO achieves the FOM of –178.2 dBc/Hz. The dual–band VCO core draws 2 mA of current from 1.5 V power supply voltage. Measured phase noise at 1 MHz offset is –117.94 dBc/Hz and –111.09 dBc/Hz in the 2.14 GHz and 4.5 GHz band. The dual–band VCO achieves FOMs of –179.8 and –179.4 dBc/Hz, respectively. The conversion gain of the self–oscillating mixer (SOM) is about 6 dB at 9.2 GHz RF frequency. Measured LO phase noise is –135.6 dBc/Hz at 1 MHz offset. The SOM achieves the FOM of –198.609 dBc/Hz.
