OK, I understand what you are doing now. I didn't realize you were holding the correction value since that hasn't been an option for me (excepting when you ping-pong between two zeroed amps). Yes, that would be probably be better if you have two different modes.
Like I said - you can
also do it in a continuous mode ,
as long as the feedback offset steps are a small amount of the received signal.
I don't see what the problem is visualizing this.
This stuff is old news you don't see it in IEEE JSSC
publications, because its been around so long.
