Pay attention to Ng fields , they are not identical amplifiers.

What about L_stage1 and Bias2 ? Should I just connect these two to Vdd ?

Should I just connect these two to Vdd ? Click to expand... L_stage1 hardly. Bias2 may be, depending on the intended quiescent current. this variable gain amplifier does not fall into any class of RF Power Amplifier ? Click to expand... What's against class A?

Bias2 is independent bias of M6
