Hi,
I have two inductors:
L1=2nH Q1=15 Rp1 (Parallel)=450 ohm
L2=4nH Q=11 Rp2(Parallel)=500 ohm
where Q=Rp/Lw
If I use them in VCO I want to know which one will provide low power consumption. I think Rp2 is greater and hence less -gm will be required to start up and hence inductor 2 will be low power consuming.
For better phase noise I think 1 is better since Q1>Q2
