hi everybody
i've a question about reference in pipelined adc.

In sub-adc there are resistor-string reference circuit.
(In one stage)
and another stage, should I use the same resistor-string reference circuit which is used in first stage??
Or made another reference circuit each stage??
 

I consider that it is better to share the same resistor chain to all stages, in order to have the same voltage references.
 

I think if the number of stage in your pipeline ADC is small, you can share the same resistor chain. If the number is large, I think use resister string each stage is better.
