Hi, guys
If I only use the MSB K bits of a nominal N bits ADC (N>K), what's the relationship between the MSB K bits DNL/INL and N bits DNL/INL.
To give the question more apprehensible, assume the max DNLs/INLs for the MSB K bit and the nominal N bits are\[ DNL_K\]/\[INL_K\], and \[DNL_N\]/\[INL_N\] separately.
Can we have the following conclusions
\[DNL_N=2^{N-K}DNL_K\]
\[INL_N=2^{N-K}INL_K\]
Or there exists other statistical relationships
Thank You!
