I am new to this site, so hello everyone!

i am trying to design a sigma delta modulator. but i am finding trouble in designing of decimation filters. can anyone please help me?

thank you.

Are you trying to do this with discrete parts on a circuit board, or are you making a mixed signal ASIC with IC design and layout tools?

i am trying to simulate a 3rd order sigma delta modulator using genaralized comb filters. i need some design examples and tips etc........since this is very new to me
