Hi,

Pipeline digital correction solves some offset of comparator, but it can't correct gain error, right?

For example, for a 10 bit adc, the first stage is 1.5 bit stage, the idea gain of this stage should be 2, but the actual gain is 1.9. Even with the help of digital correction, it can not correct the gain error? right? How to understand it?

The first stage of the pipeline should have a accuracy of 10 bit even we have the digital correction?

Thank you for your kind help.
 

Digital offset correction - as the name says - only corrects the offset, by sensing and counteracting this offset voltage. It has nothing to do with the gain.
