碩士 === 國立中山大學 === 電機工程學系研究所 === 96 === This thesis is composed of three parts. In the first part, various kinds of theory to account for injection locking and pulling in the available literature are studied and compared. In the second part, this thesis proposes an experimental setup with self-made hybrid VCO and commercially available equipments and components to measure the characteristics of injection locking and pulling. This thesis also performs simulation to verify the measured results. The simulation mainly relies on the circuit envelope technique that has been developed in our laboratory. Comparison between measurement and simulation shows good agreement in the injection-locking characteristic curves and the injection-pulling spectrum characteristics. In the third part, this thesis carries out an RFIC design for a fractional-N frequency synthesizer with special features on quantization-noise cancellation and PLL nonlinearity reduction using TSMC 0.13μm CMOS process.
