Abstract :
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.
