A.2.3.1 ATD Accuracy Definitions
For the following definitions see also Figure A-1.
Differential non-linearity (DNL) is defined as the difference between two adjacent switching steps.
DNL(i) = V-----i--1-–--L---V-S---iB---–-----1- – 1
The integral non-linearity (INL) is defined as the sum of all DNLs:
n
∑ INL(n) =
DNL(i) = V----1-n--L---–-S---VB-----0- – n
i=1
