A little thinking here. this is about SNR at each stage, as it relates to the residue of each stage in the pipeline.
More specific, it is the IRN (input referred noise) at each stage.
That said, you might want to build a math model of this. (or even just an Excel spreadsheet with some equations in it.) Keep track of the signal IRN, the residue, and look at the compounding noise vs. gain through each conversion stage.
If you put in the gains, noise, of each stage and the resulting SNR's at each output, you can define an aceptable SNR, and gain a better understanding of the noise down the chain.
