摘　　要：快速有效的频率合成器的相位噪声性能仿真可以对频率合成器的设计实现提供有效的帮助。对此我们提出了一种仿真频率合成器整体相位噪声性能的新方法。首先对在Cadence下仿真得到的频率合成器中各模块相位噪声曲线进行拟合,然后在ADS下对应建立各模块的噪声模型,通过在ADS下仿真快速得到频率合成器整体的相位噪声性能。通过仿真验证了这种方法准确、快速。Fast and efficient simulation of phase noise of frequency synthesizers can be helpful for the their design.A new method to simulate phase noise of frequency synthesizers is proposed.Based on Cadence,the simulated result,curves of phase noise in different modules of a frequency synthesizer are fitted.The noise models for different modules are constructed.Based on ADS,simulation is made to quickly obtain the general performance of phase noise of a frequency synthesizer.The accuracy and efficiency of this method is verified by simulation.
