Hi all,
I have to design an opamp in 28 nm.
So, I used Phillip Allen book as an example. However, then I was looking for Kn or Va - I found some posts (on this forum) like:
don't carry about Kn, due to short channel effect - it's relevant. or Va (early voltage) is only for old technologies, not it isn't suitable for design.
Sooo, what should I do? How to design an opamp for such low technology node if I can not use these key parameters (in my opinion).
if all tutorials which I have ever seen require parameters like Kn,Kp, V'a...
:bang::bang::bang:
Best,
Vadim
