Can the 14bit SAR ADC be realized in a 130nm process without calibration?

hi, all,
with A 130NM cmos PROCESS, does the 14bit(or above) SAR ADC can be realized without any calibration?
or does the 14bit(or above) SAR ADC can be realized without any calibration?
 

Re: about the SAR ADC

I think, no.
 

Re: about the SAR ADC

Our 12bit SAR ADC on a std 0.18µm CMOS process without calibration shows an ENOB of 10bits.
 

Re: about the SAR ADC

It depends on several parameters, but mostly how much power and area you are willing to spend.
In general, for a 12-bit (or higher) resolution ADC, some sort of calibration is a must.

Hi
Why you use 130n?
Is it better than 180n for analog design?

tnx
