wide swing op

Hi, i'm a Italian student on electronic engineering.With other two friend,we are making a project that it consists in a op-amp with current mirror wide-swing cascode.This project is my first project.The particularitity of thi project is that we must use the gm/id methodologieand we don't known the first pass to starting this project!!!
Where we can find material to help us!!!Thank for the help and we hope that anyone can help us!!!
 

current mirror op amp

First you should define your branch current base on your spec.
And then choose the each transistor's W/L ratio on your Gm/Id value.
