摘　　要：高空电磁脉冲(HEMP)能够对电子器件或系统产生不可忽视的电磁脉冲效应。选取高速比较器与时钟驱动器,采用脉冲电流注入(PCI)的实验方法研究这两种器件电源模块的电磁敏感性。试验结果表明:双指数脉冲电流的上升沿是引起高速比较器与时钟驱动器输出扰动的主要原因,且扰动幅度都受到注入脉冲电流幅值的影响;高速比较器工作在不同电平时电源模块的电磁敏感性不同;高速比较器与时钟驱动器在不同工作频率下会表现出不同的电磁敏感性。研究结果对电子器件或系统的电磁敏感性分析与加固具有一定的指导意义。High altitude electromagnetic pulse(HEMP)can produce electromagnetic pulse effects on electronic devices or systems that cannot be ignored.In this paper,a high-speed comparator and a clock driver are selected,and the electromagnetic sensitivity of the power modules of these two devices is studied by the experimental method of pulse current injection(PCI).The test results show that the rising edge of the double exponential pulse current is the main cause of the output glitch of the high-speed comparator and clock driver,and the amplitude of the disturbance is affected by the amplitude of the injected pulse current.The electromagnetic sensitivity of the power module of the high-speed comparator is different at different output level.Different operating frequencies of high-speed comparators and clock drivers will show different electromagnetic sensitivity.The results have certain guiding significance for electromagnetic sensitivity analysis and hardening of electronic devices or systems.
