Hi everyone!

i would really like some help here!!!I am on a research for my final work for taking my degree in electronics engineering and i can't move on with it. So...i would like you to help me with the topic ''A/D sigma-delta converters''!Please post me any good url that could help me...or if it's possible, if you have any projects of yours,to upload, to help me out i would be grateful!!!I prefer webpages or projects, than books,because it's a little difficult from where i am to find technical books especially in English, and i will have to wait for too many days to have it home if i order it!Please help meeee!!!Thank you all!
 

Why don't you look for it in Google first?

You can also look at Texas Intrumets' application notes about sigma-delta converters.

Thanks both...I will look at this webpages and i hope to find the informations i need. I would also like to thank especially angelot for his brilliant idea to google it!!!!!! You think i found that forum/ site but i didn't know how to google it or i didn't want/thought (about) it??? I was looking for some specific good sites because i found soooooo many at google and i felt lost.(of course i am kidding, i don''t criticize you!!!I am not ungrateful!!!) .Thank you sooooo much both for helping me!!! I really appreciate it.
 

It is maybe useful for you.
Ten years ago, A/D converter is very expensive.
At that time I used to design with R, C and timer.
check microchip 16C73 application notes
There is very old application but so good idea as far as I know.
The application note title is "Ohm meter", maybe.
Anyway you'd better go to www.microchip.com
