Hello
I wonder why foundries are not providing the capacitive load condition (CL)for the test of the given GBW and or transient behavioural like slew rate..etc
It is very known that GBW and SR are propotional to the CL, connecting higher CL for two stage amplifier will lead to different phase margin from the one plot by the datasheet or even to instability if the value of CL is large enough.
Thank you
Best Regards
