Integral Non-Linearity (INL)
It is defined as the deviation of the transfer function from a best fit straight line (linear
regression computation). The INL of the code i is obtained from the equation:
where: S corresponds to the slope of the ideal straight line (code width); i corresponds to
the code value; V
Differential Non-Linearity (DNL)
It is the deviation in code width from the value of 1 LSB.
where: V
