I want to design a cascade amplifier with differential input using mosfet with gain>3000
pls help
 

Make a Telescopic Cascode for the first stage for high gain of atleast 300. This would be easy. A telescopic itself would give a gain of around 1000 if designed well.
Make a Regular Common source stage as second stage with a gain of atleast 10. Also easy.
Put appropriate compensation for stability.

You can refer to this page for the design steps.
