Amplifier design using HSPICE

Hi guys

I have to design an amplifier with the following conditions. Since i am new in this, I need some help. Can you guide me on how to start on this?

Supply voltage = ±0.9V (Fixed)
Load condition = 10pF (Fixed)
Low-frequency gain ≥ 80dB
Unity-gain frequency ≥ 5MHz
Power consumption < 500uW
Phase at unity-gain frequency ≥ 60°
Output swing: −0.4V < Vo < 0.4V
Slew rate ≥ 5V/μs
CMRR ≥ 80dB

The circuit should not have a current source bias.

From these specs, how to choose which circuit configuration and size of transistors (.18micron technology)
