摘　　要：同步开关输出噪声是影响芯片信号完整性的主要噪声之一,较大的噪声有可能导致数字系统中元件的错误翻转。本文首先简要介绍了同步开关输出噪声的产生及特点,然后通过电路模型仿真,得到了与噪声相关的因素。最后结合实际电路,根据仿真的结果得到了控制同步开关输出噪声的方案。The simultaneous switching output(SSO)noise is important to the signal integrity and may induce false inversions in digital systems.The generation and the feature of SSO noise are introduced.Then the factors related to noise are given by SSO model simulation.Finally,based on the actual circuit and simulation results,a method for controlling SSO was presented.
