摘要
针对毫米波锁相环建立了其相位噪声模型，并在此基础上推导出系统相噪传输函数，通过分析此传输函数，可获得锁相环中各环节对系统输出相嗓的贡献，从而为提高环路性能提供了理论依据。计算机仿真及实验结果都验证了本方法的正确性，并给出了部分仿真及实验结果。
This paper sets up the phase noise model of mmwave phase-looked loop,upon which acomposed phase noise transfer function is derived. By analysing this function,the phase noise contribution ofall the parts in PLL system can be distiguished,and therefore a theoretical priciple for the improvement ofPLL performance is available,Both computer simulation and experiment Show their concordance with thetheoretical analysis. some resultS are also shown in this paper.
