tlili, thanks for you reply.
In my application, I am need sufficient gain ahead of the ZIF to toggle the ADC ~2bits above its noise floor.
If I set the 12 bit ADC to toggle at 10 bits ( calulated) on noise and the ENOB is 9 bits then I am not toggling above the noise floor of the ADC and I could miss information on the incomming signal. Setting the gain high enough to
· guarantee I am toggling on noise and if the ENOB is below my noise togle set point I will reduce the system dynamic range. This is why I need the ENOB of the part.
I would think in you layout cell library you would have the information for ENOB like you do on other ADC's.
Thanks again for any help you can give.
Rod
