Vov or Vdsat

[sherline123]

Hi, when we doing the biasing for normal opamp comparator, the biasing part meeting Vov more important or meeting Vdsat?
If the Vov is low, this will leading transistor at substrehold region.
If decent Vov, then very likely it will not meeting the Vdsat.
Just wonder which one i should sacrifice?

for normal opamp comparator

I´d differentiate between OPAMP and comparator

the biasing part

sounds like IC design. If so, please post at the IC design forum section.
