12位A/D转换器总剂量辐射效应的测试技术

Total dose effects testing techniques for 12 bit A/D converters

介绍了一种在重离子和γ射线环境下，基于计算机控制的Ａ／Ｄ转换器特性动态测试技 术，并给出了高精度Ａ／Ｄ转换器ＡＤ５７４Ａ的总剂量辐射测试数据。结果表明，对主要转换码值 直流参数与线性度的测试完全适合于Ａ／Ｄ加固设计的评估；其性能价格比优于全速动态测试 技术．

This paper described testing techniques with approved computer aided ADC characterization methods for both heavy ion and prompt gamma environments. The results show that measurements of dc parameters and linearity at major code transitions are adequate for evaluation of A/D reinforce designing, with considerable cost saving compared to full dynamic testing.
