what is ugbw

Dear All:

I don't know these two words "unity gain bandwidth(UGBW)" and "gain banwidth(GBW)", who can tell me their different?

unity gain bandwidth is the bandwith of amp when the gain is 0 dB(X1,no amplify) ;GBW is the amp closed work bandwidth ,there have a relation:1*UGBW=gain*GBW,wher "gain" is your amp circuit closed gain.
