Hi,

I am new to digital calibration of pipelined ADCs and although I have read several papers on this topic, I have difficulties in reproducing the calibration schemes when I run some behavioral tests for these.

It seems to me that I have not understood the ideas correctly, and so am making errors when implementing the schemes.

It would be nice if someone could suggest a reference where atleast 1 detailed example is worked out showing how exactly the error is computed, scaled and removed.

Alternatively, if someone can provide a simple example of the same, that would be do just as well.

I am largely looking at schemes where the error in the transfer curve is measured by using later stages of an ADC and the result is used to correct the nonlinear transfer curve.

Thanks
Vivek
