Title: Capacitor Selection in Sigma Delta Modulators
Post by repah on Aug 13^th, 2019, 10:24am

Hello,

I am designing 3rd Order, Single Bit, CIFF Discrete Time Sigma Delta Modulator.

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.
