Hi, I have an application where I need low power consumption. I have chose the AD8011 and supply it +-1.5V to minimize power consumption.

However I need some bandwith and amplification. I have a signal of 0-0.05V at 20MHz. I amplify it 11 times. And I get about 4MHz of bandwith out.

If I crank up the supply voltage to +-5V, I get the bandwith I need. But too much power loss.

My feedback is 1k:100R. Tried 470R:47R too, and got slightly higher BW.

What do I do to get 20MHz at +-1.5V power supply?

Thanks!
