I haven't worked with active inductors for some years, but do you think it is a good idea to use the active inductor in the LNA? Because it is very noisy. About the absolute inductance value I think you can do either a simple calculation or use a simulator to estimate it. Be careful about the Q. If I design this LNA, I would prefer to replace the inductor between the cascode stage to extend the bandwidth, and hope the noise contribution is not too high. I will not consider to use the active inductor at the load.
