| Abstract: | This paper discusses the design of phase-locking frequency synthesis oscillator with low phase noise, and analyses and discusses the main causes for its phase noise such as loop filter, frequency divider, phase discriminator and voltage control oscillator(VCO). Furthermore, it points out how to design loop filter and VCO to get optimum phase noise performance under pre-selected phase discriminator and phase divider. |
