摘要
本文简单介绍了数字芯片ADC(模数转换)模块,并以精度为3位ADC为例,针对其常见的失效模式进行了分析。特别针对零刻度误差,满量程误差,增益误差,微分非线性误差,代码缺失误差做了分析,指出每种误差产生的原因,给ADC带来的影响,并提出了减少误差的基本方法。
Had introduced digital microcontroller ADC (Analog-Digital conversion) module, and took 3-bit resolution ADC for instance, to analyse the fault category, especially referring to offset error, full-scale error, gain error, differential non-linearity error, missing code error. Had pointed out the root cause of each fault, the influence for ADC module, and had advised the general method to decrease error.
