I am trying to build a high Q resonator at 15MHz using op amps. The trouble that I run into is that when the Gain-Bandwidth Product of the op amps is low the resonance shift dramatically and the Q-factor drops. In the attached picture I have shown a circuit diaram, the intended transfer function and the Bode diagrams for a case where GBP is 50MHz and where it's 20GHz. At GBP of 20GHz the frequency response is very close to what I expected/intended it to do (which is resonance at 15MHz).
So what I am really seeking help with is how one can improve GBP perhaps by combining several op amps (if it's something possible) or some other way. I would also appreciate any suggestions on some op amps with high GBP. By high in this case I mean hundreds MHz to a few GHz or higher.
Thanks
