Hi, all,
I am designing a switched-capacitor S/H circuit, and from some documents, I found that the opamp used in the circuit takes use of a switched-capacitor CMFB, what I want to know is that, why this specific CMFB should be used here, but not a general CMFB circuit?
and also any literature about this switched-capacitor CMFB is welcome.
Thanks in advance!
