High GB opamp for active rc filter

[Megh]

Hi,
Want to design a fully differential opamp used in active rc leap-frog filter composition. Filter amps has 14pF and 15K resistor in the feedback.
Gain requirement is 45dB min and GB should be 120MHz. 65nm 1.2V supply.
Tried standard 2 stage fully diff topology with miller comp. That consumes approx 1mA per amplifier. Want to reduce the current further.
Please suggest me any topologies.
Thanks

Why not a 2 stage opamp with just current gain from the 1st stage to 2nd stage. Use the output pole as dominant pole. This is better for high Bandwidth one that you need (vs folded cascode)
