Title: sigma delta modulator for pll
Post by Esther on Dec 13^th, 2006, 7:43pm

Dear all,

I start to design sigma delta modulator for the pll. but i am really junior in this field. Anybody here can give me some advices on how to begin step by step for this design?

Just read Ken Martin's book on modulator. It seems it is a analog sigma delta modulator. If i am not wrong, commonly pll use digital modulaor, right? I need write Verilog code, right? Where can I find source Verilog/VHDL code for my reference

Thank you very much for any of your word..

Esther

Esther,

Where do you want to use this Sigma Delta modulator?
Is it in the feedback divider??
