sigma delta ADC modulator

[kuohsi]

Hi all, i am a rookie of this board,
I have learned sigma delta ADC
Now I try to implement a very basic 1st-order sigma delta ADC
but I can't simulate it yet , I am in helplessness,
Dose anyone has a working basic circuit diagram & simulation result?
thank you very much!!

hehe, i am in same situation with you .

I am designing an 14-bit DAC with self-calibration circuit which contains a 16-bit sigma-delta ADC, i am new to ADC, tough job! Could I finish it in two months?

If you have strong analog ic design background ,and if you focus all your working time on it ,maybe you can finish it in two months.
