Your question is Amplifier Tail Response and PSRR. Take a moment with it on the right.
Talk me through your thinking if you like. When you're confident, submit your answer and I'll grade it like a real screen (7/10 or better passes).
Explain how you would analyze tail node response in an amplifier for both small-signal and large-signal cases, and derive PSRR in open-loop and closed-loop configurations.
