摘要 电流源的失配是制约电流舵D/A转换器精度的一个重要因素。它是一个随机现象,需要用统计的观点进行分析。两个晶体管之间的失配,既与晶体管尺寸有关,又与晶体管之间的距离有关。以往的分析中,只考虑了尺寸相关项,而忽略了距离相关项。文章分析了基于距离相关项的随机误差,推导出每个数码的INL表达式,并用Matlab对不同开关序列下D/A转换器的成品率进行仿真,得出用SG算法优化开关序列,可大大减小距离相关项的影响。 The mismatch of two identical MOS transistors attributes to both the dimensions of MOSFETs and the distance between them. Previous works were done only based on the size-dependent term, with the distance term neglected. In this work, random error related to the distance term was analyzed, and the expression of INL for each code was calculated. The yields of DAC for different switching sequences were simulated with Matlab. It has been shown that the effect of distance term could be greatly reduced for SG arithmetic switching sequence.
