12.1.1 Non-linearities
12.1 Definitions
Integral Non-Linearity (INL).:
from a best fit straight line (linear regression computation). The INL of the code i is
obtained from the equation:
where
S = slope of the ideal straight line = code width; i = code value.
Differential Non-Linearity (DNL).:
1LSB.
