Glacier,

  Just for completeness, there is also some additional information at:

Sigma-Delta ADC Priciples and Architectures
http://www.imse.cnm.es/esd-msd/WORKSHOPS/MIXMODEST/PRESENTATIONS/LPSDM_Architect...

Errors in Sigma-Delta ADC  
http://www.imse.cnm.es/esd-msd/WORKSHOPS/MIXMODEST/PRESENTATIONS/LPSDM_Errors_v2...

Design Example:
http://www.imse.cnm.es/esd-msd/WORKSHOPS/MIXMODEST/PRESENTATIONS/medeiro1_exerci...

In particular, the error presentation discusses the relationship between different design
parameters, for example, open loop gain,  and ADC performance.

                                                                                       Best Regards,

                                                                                           Sheldon
