摘要
12位以下D/A变换的静态误差(包括线性误差和微分线性误差等)主要取决于其电阻网络的精度。根据要求的静态误差限制值来确定网络电阻的容差,或者由已知电阻网络来预测和分析D/A变换的静态误差,是D/A变换研制工作中的一项重要工作。本文提出用蒙特卡洛法来进行这项计算机辅助分析,并以10位D/A变换为例说明仿真过程。文中提供的方法和给出的结果可供有关工程技术人员参考和引用。
The statical error of a D/A converter (linear error and differential error) is mainly determined by the precision of the resistor network of D/A converter. One of the main work in designing a D/A converter is to determine the tolerance of network resistors according to the desired statical performance, or to predict and analysis the statical error of D/A converter for a known resistor network . In this paper, the Monte-Carlo computer simulation approach is proposed for such CAA. Finally, a 10-bit D/A converter is taken as an example to illustrate how the CAA is realized.
