How to select the capacitors sizes for this design ? See attachment. CT - total of ff - feedback capacitors. I know how to select CS1 based on my noise requirements. But how do I select the other capacitors sizes like Cff(x) and Cs(x) etc. Thank you. Attachments SigDelt.png 39.2 KB · Views: 123

Based on Integral capacitor value. It is determined by current consumption.
