可能是我的DAC的电容阵列有问题？是基于Vcm和冗余还有电容复用构成的DAC，原来跑的是采样频率30M，9.86的 ...

Over sampling 目的只能减少 quantizer 产生error ,

sigmaDelta 有两功能 , oversampling + noise shaping

只有 Over sampling

SNR 公式 = 6.02*N + 1.76 + 10 log (M)

多了 noise shaping 后

SNR = 6.02*N+ 1.76 -5.17 + 30 log(M)

别问我 5.17那来书上看到听说一堆推导来 ..

你看 Anenergy efficient noise-shaping SAR ADC in 28 nm

VLSI2015_Passive Noise-Shaping SAR AD

没做过这类 ADC 拉

怪怪

刚upload 都不见

Eetop 出什问题啊

哥，这个论文您知道在哪下载么？您知道在哪下一些国外的硕博论文不
