Hi,there
We know that the closed-loop gain is the reciprocal of feedback factor f, that is , Acl=1/f. Then from the architecture of the S/H shown in the pic1, we can conclude that the feedback factor is same as pic2. The S/H should have a closed-loop gain equal one, but at this time ,the reciprocal of feedback factor f is C\[{ S}_{ }\]+C\[{ F}_{ }\]+Copamp/C\[{ F}_{ }\]>1. I dont know why they conflict each other, any hint?
