Hi,

Could you please help me with part 2 of attached problem? I got the dominant pole location to be 30 KHz, because the required phase margin is 45 deg, which implies that the phase at UGF=3MHz is 45 deg, which means 3*45 drops, so the pole is 3 decades inward.

But I can't seem to compute what maximum bandwidth is.
 

So sorry, I forgot to add the attachment! Here goes. Untitled.png
