摘要
研究了传导电磁干扰下，数字信号控制器的电磁抗扰性能预测与分析。针对一种典型32位数字信号控制器，设计了基于直接功率注入法的敏感度测试平台，测试得到了敏感度阈值；并通过S参数测量、输入输出缓冲器信息规范（IBIS）参数提取，建立了集**数的电磁敏感度仿真预测模型。模型仿真结果与测试结果在10 MHz到1 GHz内具有较好的一致性。
Abstract
This paper used the direct power injection method to obtain the conducted immunity of low-dropout linear regulator (LDO) under electromagnetic interference. And a cascade model of linear filters and Taylor series representation of nonlinear system are proposed for immunity simulation. In addition, the traditional modeling method was used to model the linear device on the test system. Finally the immunity simulation of LDO was carried out and the results show that the model in the 1 MHz-2 GHz range has a good fit between simulation and measurement.
