Analog-/Digital-Wandlervorrichtung

摘要

The invention relates to an analog-digital converter with n comparator devices having a first and a second input and n reference-potential generating devices for applying an individual reference potential to a corresponding comparator potential device, wherein the comparator devices are connected to the analog signal to be converted in the first input and to the corresponding reference potential in the second input. At its output, the i-te comparator device supplies a bit with a given valence i of the digital signal corresponding to the converted analog signal. The highest-valent bit Q(n) has an n valence. The i-te reference-potential generating device is configured in such a way that it regulates the reference potential to be applied in the i-te comparator device depending on the fed-back bits whose valence j higher than i is, n, i, j being natural numbers and the relation being 1
