在本研究中我們將試圖要以單一的壓控震盪器架構,設計改善一般壓控震盪器相位雜訊不好的缺點,嘗試以設計諧振電路配合壓變電容之方式進行改善。實際的VCO最後仍必須加以封裝,由於封裝的寄生效應,可能導致VCO內部干擾以及頻率飄移問題,其準確解有賴於全波數值電磁模型之建立。我們希望建立HFSS(High Frequency Structure Simulator)結合ADS軟體的模擬流程,能夠在設計VCO初期,就可以預測其封裝後的頻率響應與性能參數。藉由實作與VCO量測,發現模擬與量測結果相當吻合,顯示我們的研究能節省產品設計所需的時間與成本。
In this thesis, voltage-controlled oscillators (VCOs) with improved phase noise are designed and implemented. In the design of the resonant circuit varactor diodes are employed. In practice, a real VCO has to be packaged. The parasitic effect of the package may generate crosstalk inside the VCO and result in frequency shifting. To obtain an accurate prediction, a full wave model is developed. A simulation procedure is established combining High Frequency Structure Simulator (HFSS) with Advance Design System (ADS) software to predict the frequency response at the initial stage of the VCO design. Prototypes have been constructed and the characteristics measured. The simulation agrees with the measured results well. The obtained result show that our study can be used to cut the development time and cost.
