Hi,
Does anyone know a good paper covering the use of correlated double sampling in switched-capacitor circuits in detail? I am specifically looking for a paper where the various noise and speed metrics are quantified so that one may design such a circuit optimally. The standard papers on CDS or chopper stabilization mention the concepts but leave it at that, and the important tradeoffs such as impact of various parasitic caps, the error cap etc. are never forthcoming, nor is a good analysis of the noise from the opamp in such cases.
If there is a good reference, it would be great. I did some hand analysis of a circuit I have but after a while, the equations get out of hand, and it is quite hard to verify them. Maybe, a good reference can help in choosing important design parameters carefully, even if the equations are not 100 % rigorous.
Regards Vivek
