Opamp Output stage - urgent

[optimistic_guy]

Hi,
I have designed a cascode differential amplifier which provides a gain of 80dB, and GB=50 Mhz. I need an output stage which delivers a load of R=10K and C=2pf and without killing the gain. Which is the best output stage which i could use ? I tried implementing the push-pull amplifier(Given in Jacob baker), but had some problem with voltage swing, i would require rail to rail voltage swing (+-2v) with a (+-2.5 v supply).
Kindly do suggest me an output stage (with references)

If you want rail to rail swing, you probably have go with class AB output.
