Urgent Project HELP!!!!

Hi all!!!

I have a project and I am having problem with
Hope you guys can help me out!!!!
Thanks in advance

I need to design an opamp with the following specifications/parameters
- operating power supply (Vcc) = 1.8V
- quiescent supply current = 600uA
- input common mode (Vcm) range = 0.2 to (Vcc-0.2)
- oppen loop gain = 80dB
- phase margin = 50º
- CMRR = 60dB
- PSRR = 60dB
- output voltage swing (peak-peak differential) = 2.8V
- small signal 3dB bandwidth = 80MHz
- positive slew rate = 100 V/us
- negative slew rate = 100 V/us
- 1% settling time = 50ns
- closed loop, unity gain, ouput impedance @ 1Mhz = 3ohms
- capacitive load drive = 20pF
- resistive load drive = 1k
- input offset voltage = 10nV
- bandgap voltage = 1.2V

All i need is a design topology that I can start with
and be able to show a gain and PM at 1.8V, 25ºC.
the opamp would have to be fully differential, which mean CMFB is required.

once again thanks in advanced
