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----_Bⁱ---^–----¹- – 1
The integral non-linearity (INL) is defined as the sum of all DNLs:
∑ INL(n) = n DNL(i) = -V----n----–-----V----0- – n
