摘要

为了找出增量- δ - σ ADC (I-DS-ADC)的噪声传递函数(NTF)特性与稳定性之间的关系，研究了40000个不同的NTF。给出了一种快速、简便的判断4阶I-DS-ADC的NTF是否可能稳定的判据。与最近的标准相比，新的标准快速且易于使用，涵盖了更多种类的可能的NTFs。

An empirical study of the stability of 4th-order Incremental-ΣΔ-ADCs

In order to find relationships between Noise-Transfer-Function (NTF) characteristics and stability of a Incremental-Delta-Sigma ADC (I-DS-ADC) 40.000 different NTF has been investigated. A fast and easy to use criterion to determine, if an NTF of an I-DS-ADC of 4th-order is likely to be stable was found. The novel criterion is fast and easy to use and covers a much bigger variety of possible NTFs compared to recent criteria.
