Thank you very much, this makes sense,
So this shift should be applied between sample/hold and input of comparator, increasing the input voltage by an amount of 1/2 LSB, am I right?
Is this the common practice for rounding sample values, because although many books about digital audio states that the sample values are rounded to the closest quantization interval, i couldn't find an example or block diagram showing that kind of shift, so i started to think that the reference values coming to the comparator might be shifted accordingly; but again couldn't find any info
Forgive my ignorance in electronics, i just want to understand how this issue is handled in a within a commercial audio AD converter
Thanks again
