Any diff of Gain BandWidth Product and Unity Gain BandWidth?
There are 2 different parameters
Gain BandWidth Product and Unity Gain Bnadwidth.
My Question:
What's the definition of the two parameters?
What's the differences between the two parameters?
In general,Which is bigger?
In general,When we choose a element such as OP,which one we should take it into consideration?Which one would be ignored compare to the other one?
I post the same topic in another BBS,someone said the two are same,But why must we define the two different parameters even they are same.
ThankS

Both Gain bandwidth product and unity gain bandwidth are same... At unity gain , the gain bandwidth product becomes unity gain bandwith...

For a higher order system (multiple poles/zeros), unity gain frequency would be usually
less than the gain bandwidth product (because each higher order pole creates 20 db/decade
and unity gain frequency would occur faster)
