Title: Digital filter design for incremental delta-sigma ADC
Post by Berti on Aug 14^th, 2012, 11:10pm

Dear all,

I am struggling with the design of a digital filter for an incremental delta-sigma ADC. Basically what I am interested in is only the DC value, right? Is a CIC filter really the right choice in this case?
Does anybody know any literature about the design of incremental delta-sigma ADCs (particallarly the optimal digital filter design)?
Any advices are welcome?
