Hello,

I am designing a 5th Order Sigma Delta Modulator - Discrete Time, with Single Bit Quantization.

I am following the procedures of:Understanding Delta-Sigma Data Converters by Temes.

In the text, they have example of 5th order modulator with following schematic, attached here.

My question is in regards to capacitor selection.

The book talks about the capacitor ratios but not about the actual values of the capacitors in the system themselves. How does one go about selecting and sizing the capacitors in this 5th order discrete time delta sigma modulator ?

Thanks.
