Can anybody tell me which capacitor (MOM or MIM) is better to use in a SAR ADC? And what are their main differences in terms of parasitic and mismatch?
Thanks in advance.Best regards,
In terms of parasitic an mismatch MOM probably better. But commonly used are MIM's.
Probably it's first becauce to have same capacitance for MOM requere much mor area that for MIM, and second it's because MIM have more precice and reproducible technology that MOM.
So I suggest you to use MIM.
