Looking for resources about making decimation filters to put after Sigma Delta Modulators.

I know Temes book has some ideas, but are there any other resources for this ? I want to implement using logic using gates or verilog blocks.

Do I just have to look at papers ?

For example the Hogenauer filter which is covered in Temes book but looking for other resources specific to Sigma Delta converter decimation filter design.

Thanks.
 

What's your specific question? The CIC algorithm is simple and implementation is straightforward and explained in many text books and papers. The best explanation is probably in the original Hogenauer paper.
 

I want to know how to implement it using logic (counters, flip flops etc) - I know the paper can be straight implemented in HDL and just synthesized. I want to make the "gates" myself.

Any resources on the actual implementation using logic ?
 

The building blocks in Hogenauers structure are adders and DFF. You can implement it directly in discrete logic.
