本論文描述如何設計金氧半壓控振盪器。第一部份討論環形振盪器,其架構為雙交叉耦合對(cross-coupled pair),採用內在共振調諧電路,具有nMOS 和pMOS 以提高負電導。此壓控振盪器由TSMC 0.35µm工作電壓3.3V,頻率1.7616GHz~2.466GHz;另ㄧ方面討論LC 壓控振盪器包含LC 交叉耦合振盪器、雙頻LC 壓控振盪器、互補考畢子壓控振盪器及互補考畢子閘極回授壓控振盪器等等。LC 壓控振盪器使用0.18µm CMOS工作電壓1.8V製程製造完成,並經由Cadence中的Spectre RF軟體模擬驗證。
Design of CMOS Voltage-Controlled Oscillator (VCO) will be investigated in this thesis. First, ring oscillator architecture is the complementary nMOS and pMOS cross-coupled pair to enhance the negative conductance with internal resonator. CMOS VCO’s are implemented using TSMC 0.35µm process with 3.3V supply voltage and frequency tuning range 1.7616GHz~2.466GHz. Otherwise, LC tank voltage control oscillator includes LC cross coupled VCO、dual band LC VCO、complementary Colpitts VCO and complementary Colpitts VCO with back gate coupling. The LC tank VCO is implemented using TSMC 0.18µm process with 1.8V supply voltage. The simulation results with Cadence Spectre RF aid the design of these VCO’s.
