i want to create a slide conference about switched capacitor.this topic is created that i shared my result soon.
thanks
thanks

The reason for using switched-capacitors in an analog IC is that it's much easier to fabricate accurate capacitors than accurate resistors, so a switched-capacitor can be (and is) used to emulate a resistor.
For higher value resistances the switched-capacitor is also smaller than the resistor.

......in this state is gain open-loop is infinite;
yes,when we sue switched capacitor ,the loop gain is not closed and we will have deal with infinite gain.No - I don`t think so because of the switched capacitor in the feedback path.
yes,when we sue switched capacitor ,the loop gain is not closed and we will have deal with infinite gain.
because i study in razavi book,we have two mode:sampling,amplifyingNo - I repeat: The loop is closed continuously.
Please, can you explain why and under which conditions you would think that the loop is open?
...we have two mode:sampling,amplifying
so when is mode sampling c3 open,c2 short
in amplifying mode c3 short,c2 open :
in replying my question,i concluded that yes,this is a gate that guides us to using digital circuits.
thanks from all for contribution.good luck
