Hello All,
I am designing 12 bits asynchronous sar adc 10Mhz sampling frequency and I am done with the layout and it works good with pex but C only (I mean that I extract only capacitor not resistance) but when I tried to extract RC pex the enob became worse about 2 bit less so I am asking what will affect my enob I mean these resistors added by extraction or what?
Thanks in advance.
Regards,
Amr
