摘要
本文研究了锁相环的建模方法，包括系统建模和相位噪声建模，详细介绍了两种建模技术的具体算法，并且介绍了针对两种算法进行应用而自主开发的建模工具。该工具针对系统建模，采用了迭代算法；针对相位噪声建模，采用了叠加算法，均能建立准确模型。在文中同时附上了两种算法的部分程序。通过该工具的应用，填补了锁相环建模工具的空白。
This paper makes research on Phase Lock Loop modeling, including systematic and phase noise modeling, it introduces the principle and methods of modeling and design, and demonstrates the self-designed software from CORPRO. Related software applies iterative arithmetic on systematic modeling and applies superposing arithmetic on phase noise modeling. This paper also attaches some programs. The application of this software will supply a gap on PLL’s tool design.
