Switched Cap based System Noise Analysis

$

Hi,

      I am very new to noise analysis when it comes to switched capacitor based system. In my system I have a comparator which goes into unity  feedback mode with some frequency. I have also a capacitor which either connects from input of comparator and ground or input of comparator and input to be compared. Apart from that  I have some set of capacitors which gets connected or  disconnected to input of comparator and ground or input of comparator and some supply. 

 Apart from this, I have a bandgap charge which is being compared with input charge. I also have to look noise coming from there also. 

    I am interested to do noise analysis to this system. I have seen some thread,  but I couldn't understand how should I go about this circuit. I would be very thankful , if someone can help me doing this.

 

Best  Regards

Abhishek
