can anyone help out with the design equations for the below 2 stag opamp.

Hi, can you specify more exactly what do you need?
Calculate gain? The value of compensation capacitor? Or smth else?

i need to calculate the W/L ratios for the transistors based on the gain, icmr ,slewrate and all

I don't think this is an unrealizable task for handy calculations. Try CAD tools for this purpose.
