Hi, all: this is a three stage OPA, now I have a question:
please look at the OPA in the attachment, In this OPA, when we design this OPA, we assume the third output voltage swing is 0.5v-4.5v.
But if we assume the output voltage swing is 0.5v-4.5v, how to confirm the voltage swing of the second stage? or say, what is the best value of the voltage swing of the second stage?
