ADC INL/DNL code density testing help

[jeep26]

Hi Guys,
Could you please help me on the derrivation of offset and amplitude formula being used in the computation of ADC INL and DNL using code density testing.

below are the formulas.

Appreciate any help.

Regards.

Welcome to the PF.

What is the context of the question?

hi berkeman,
The formula offset and amp indicated in the lower right of the diagram are used for curve fitting to compute for the INL and DNL using code density testing. I can't figure out how the C1 and C2 were derived.

Thanks for welcoming me.
