Hello to everyone, I am building a personal amplifier. I have this output stage and vas:
How to implement the error correction method by Hawksford or Cordell instead of the static bias with this configuration?

You should be more specific. What do you mean with "instead of the static ..."? On first sight, there seems to be no general difference to the situation in the circuits proposed, for instance, in Cordell's book.

More specific? This is the error correction amp done by Bob Cordell:
Findable in his PDF on his website: http://www.cordellaudio.com/papers/MOSFET_Power_Amp.pdf
There the error correction by Hawksford:
I want to implement them in my amplifier specific configuration.

There was an article in EDN on output error correction, but I can not find my computer copy, I will have to look in my paper stacks. Maybe someone else will remember it and post it. It looked very good, at least to my untrained eyes. Good Luck. Thanks
Here is that article.

I hope it helps what you are trying to do. Thanks

That Cordell circuit resembles very much a circuit with negative feedback.
Where should we draw the line between error correction and negative feedback?
