非线性混合信号系统如CP-PLL的分析是具有挑战性的，因为控制系统的一般理论不能很容易地应用。因此，CP-PLL在模拟平台中设计，在晶体管、行为或线性级别上对其进行描述。这些模型往往是无利可图的表征能力，模拟时间和计算机资源时，考虑到非理想的效果。为了避免这种情况，可以使用模块化和增强的事件驱动模型。由于该模型不适用于联合收割机的相位噪声和非理想效应的结合，本文的重点是在事件驱动表示的相位噪声建模。此外，死区对相位噪声的影响的分析描述，以获得优化和鲁棒的系统设计。
The analysis of non-linear mixed-signal systems like CP-PLLs is challenging because general theory of control systems cannot be applied easily. Therefore, CP-PLLs are designed within simulation platforms describing them on transistor-, behavioral-or linear-level. These models are often unprofitable according to the characterization capability, simulation time and computer resources when considering non-ideal effects. To avoid this, the modular and enhanced event-driven model can be used. Since this model is not applicable to combine phase noise and non-ideal effects, this paper focuses on modeling phase noise within the event-driven representation. Furthermore, an analytical description of the impact of dead zone on phase noise is given to obtain an optimized and robust system design.
