  • RE: ADS1256: ADS1256用户手册给出的ENOB公式，按照课本的推算公式，ENOB后面需要再减去1.79。为何ADS1256用户手册中没有减去1.79。

    您好，按照这里的公式，准确的推到没问题，需要减去ln(6)=1.79. 我看了几款delta-sigma架构的ADC器件，ENOB的计算都是没有减去1.79， 数据手册中应该 是估算。 另外，大多数SAR型的ADC，您应该经常看到，常用的ＥＮＯＢ的计算公式为 ENOB = (SINAD - 1.76dB) /6.02。　 关于ENOB的计算公式，可以参考这篇Analog Engineer’s Pocket Reference： https://www.ti.com/seclit/eb/slyw038c…

    这两个图可以从下面文档figure45和figure47清晰的查看，上面我说错了，这两个图只能应用在二阶系统中。 Analog Engineer’s Pocket Reference： www.ti.com/.../slyw038c.pdf 过冲百分比和交流增益峰值与相位裕量的关系公式可以参考下面链接文档Appendix B部分： www.ti.com/.../tidu032c.pdf
