Hi Altruists,

I need to design an incremental sigma delta ADC (OSR=500) where I need to implement a CoI Filter. From literature study i found that this CoI filter is actually same as CIC but without the comb part for CIC. I need to write a code in Verilog (or Verilog A) for CoI Filter. I dont have so much deep knowledge on CIC. I checked some verilog codes on previous threads but i am messed. can anybody please give me some potential links to codes with description how it is working? It would be great help. Thanks.
