摘要
本文提出了一种新的分析4级多径环形振荡器相位噪声的方法。该方法利用广义阿德勒方程来描述锁定动力学，并假设噪声是施加于稳态解的小信号扰动。通过求解微扰微分方程组，导出了相位噪声的计算公式。然后，在0.18 um CMOS工艺下对多径环形振荡器进行了仿真。仿真结果与所提公式吻合较好。
In this paper, a novel analytical approach is proposed for phase noise of 4-stages multi path ring oscillators. The method utilizes the Generalized Adler's equation to describe the locking dynamics and assumes the noise as a small signal perturbation applied to steady-state solution. By solving the system of perturbation differential equations, the formula for phase noise is derived. Then, the multi path ring oscillator is simulated in 0.18-um CMOS technology. There is good agreement between simulation results and proposed formula.
