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:
- Why the feedback lines are being substracted not added ?
- How to determine to values for coefficient ?
- Why people sometimes put integration scheme before the comporator ?
Thanks in advance.
