For the following definitions see also Figure 110.
Differential Non-Linearity (DNL) is defined as the difference between two
adjacent switching steps.
DNL(i) = -V----ⁱ_1--^–--L---VS----ⁱ-B--^–---¹-- – 1
The Integral Non-Linearity (INL) is defined as the sum of all DNLs:
∑ ^{INL(n) = n DNL(i) = V---1--n-L---–-S----VB----0- – n}
i=1
