doubt about implementing ome inductors

I desined one ultra wideband LNA that works in 3.-10.6 GHz. in this LNA, values of two inductors are 0.3nH. The performnce of my LNA is good ,but i dont know these inductors are implementable. I searched some paper ,but i did not find any inductor with value less than 0.5 nH. I want to know implementing small inductor are common or no? and implementing small inductors are difficult or no? PLease help me to get insight about this subject.

Best regards

0.3 nH is a value comparable to most parasitic values of the RF components.
So, just find these parasitic values and integrate them in your design.

Hi
Thank you for your attention

I did not understand that my design is reliable for implementing on chip or no?

If I understand right, these two inductors are the only inductors you considered up to now in the analysis of your circuit. I'm not involved with IC design, but I guess they can be implemented. Actually your circuit has a lot more of inductors in a similar order of magnitude, at least all bond wires and more parasitics as pad capacitances. To decide if your design is reliable for implementing on chip, you should proceed to a real world analysis of your circuit as a first step.

Are these inductors are in shunt or in series, let share the schematic design to help you better.
