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

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

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
