Can any one tell me how to find the gain bandwidth product from bode plot of a unity gain circuit for the attached bode plot?
I hv attached the circuit and bode plot .....
Gain bandwidth is just the gain times the -3db frequency if it is a DC circuit from 0Hz to -3dB frequency.
In your case, your circuit has a gain of 1. Your -3db from the top graph is about 370Khz, so the GBWP is about 370KHz.
You must be looking at a different attachment than me yungman. The -3dB point is shade over 2MHz and the gain of each op-amp is 2.
The numbers may have been changed slightly but this is basically the exact same question as the other poster gave. I'd say this is a class assignment and the instructor has changed the figures slightly for each group so as to minimize cheating.

Ha ha, what? Look at my post again!!!!:rofl:
When I saw your comment and look quickly at the plot and schematic, I thought it's the same drawing. So I pulled up the numbers from before. But the message is the same. This is scary!!!
