Design and Implementation of Voltage-Controlled Oscillators with the Full-Wave Simulation of the Package Effect

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.
