Do the MOSFETs have part numbers or are they devices that are part of some ASIC? Is Vdd the recomended voltage and quiescent current for these devices? Is this going to be used in a practical circuit?
As a starting point I would set DC bias to be about half of Vdd. This should cause M1 and M2 to have the same drain to source voltage and allow both to run in the linear region. If Vbias is too high, M1 will try to conduct too much current, saturate and not operate in its linear region. You may have to adjust Vbias to find the highest gain. If this doesn't work, try increasing Vdd and repeat.
I would also set Cd and C3 to zero as they affect AC gain. You can restore them after the DC operating conditions are properly set. I expect C3 set to 10p is way too high for 2.4 GHz.
