There are a lot of variations of DFEs online.

But I couldn't find a step by step explanation on how for example the 2-tap DFE works. Can you provide an explanation with a scheme ?

I looked for some articles and have same specific questions also, like:

  1. Why the feedback lines are being substracted not added ?
  2. How to determine to values for coefficient ?
  3. Why people sometimes put integration scheme before the comporator ?

Thanks in advance.
