摘　　要：A/D转换器在航空航天系统中的重要元器件,随着器件转换时钟频率不断提高而其工作环境不断恶化,如何准确测试其时间参数对于全面评价A/D转换器性能特别重要。目前对于高速A/D转换器时间参数测试,主流方法是通过示波器直接测试其输出,该方法对于示波器采样速度要求比较高。文章提出一种高速A/D转换器时域重构技术,可以通过计算机数字信号处理方法来实现高速A/D转换器时间参数测试,同时避免对示波器采样速度的依赖。同时,在研究高速A/D转换器时域重构技术方法及其应用的基础上,通过了相关试验验证。High-speed A/D converters are important components in equipment,and their working environment is deteriorating with the continuous increase in device conversion clock frequency.Accurately testing the time parameters is particularly essential for comprehensively evaluating the performance of A/D converters.Currently,the time parameters for high-speed A/D converters are primarily tested by directly testing the output through an oscilloscope with a high sampling speed.In this study,the time-domain reconstruction of high-speed A/D converters is proposed.It can be used to test the time parameters of high-speed A/D converters through computer digital signal processing and avoid dependence on the sampling speed of oscilloscopes.Moreover,by studying the time-domain reconstruction of high-speed A/D converters and its application,this study verifies the correctness of the principle through experiments.
