Digital filter design for incremental delta-sigma ADC
Aug 14th, 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?

BR
