Decimation filter for multi-bit delta sigma
Sep 06th, 2013, 2:14pm  
Hi,

I appreciate if someone helps me figure out how I can design a decimation filter for a multi-bit delta sigma ADC. I could find some stuff but all of them were for 1-bit delta sigma.

Not very different from single bit delta-sigma. See e.g.
Shankar Parameswaran and Nagendra Krishnapura, "A 100µW Decimator for a 16 Bit 24kHz Bandwidth Audio ΔΣ Modulator," 2010 International Symposium on Circuits and Systems (ISCAS), Paris, France, 31 May-2 Jun. 2010.
