本論文描述如何設計四相位壓控振盪器,主要分成二個部分,第一個部分為新式低功耗之變壓器耦合技巧四相位壓控振盪器,使用UMC 0.18um CMOS 1P6M製程。其架構利用了電流再利用電路型式與變壓器耦合產生四相位訊號的技巧,使其具有低功率消耗的特性,工作電壓為1.8V,可調變頻率為2.04GHz~2.2GHz;第二部份為討論背閘極耦合式四相位壓控振盪器,其製作使用了TSMC 0.18um CMOS 1P6M製程,架構中使用了平衡式壓控振盪器型式,並利用背閘極耦合技巧產生四相位訊號,工作電壓為1.8V,可調變頻率為5.26GHz~5.59GHz。經Cadence 中的Spectre RF 電路模擬軟體的驗證,朝著低相位雜訊和低功率消耗來設計。
Design of Quadrature Voltage-Controlled Oscillator (QVCO) will be investigated in this thesis. This thesis is mainly composed of two topics, the first is the novel low power based on transformer-coupled technique quadrature VCO, the chip is fabricated by the UMC 0.18um 1P6M CMOS technology. The structure uses the current-reused topology and transformer coupled technique to generate quadrature signal, and it can achieve low power characteristic. The operation voltage is 1.8V and tuning range is 2.04GHz~2.2GHz. The second is the quadrature VCO using back-gate coupled method. The chip is fabricated by the TSMC 0.18um 1P6M CMOS technology. The structure uses balanced-VCO topology and body-coupled method to generate quadrature signal. The operation voltage is 1.8V and tuning range is 5.26GHz~5.57GHz. From the simulation results with Cadence Spectre RF, the design has been done with the goal of low phase noise and low power consumption.
