Tutorials and materials about SAR ADC

[olzanin]

Hello,
next time I will take part on some 12bit SAR ADC workshop. I'm an newcomer on this ADCs, I know only coarse how they works.
And I want ask some interesting questions!
Can somebody help me?

Thanks

Re: SAR ADC Question

Dear all,

I design my sar adc. My input is signal-end. My (p) input's common mode is

0.425V and my peak-to-peak is 0.8V. In the chip, my input is 0.4V so the input

has some offset. I run simulation and my comparator's input's ENOB is bigger than

4.5. But my AD output's ENOB is 3.7. Why? If My (p) input's common mode is

0.4V, my AD output's ENOB is bigger than 4.5. Why is the offset doesn't affect

S/H's output? Thanks.
