I would like to design multistage LNA to improve gain. I used inductor between one stage to next stage since inductor will bypass dc components. What best circuit or component can be used to connect one stage to next stage and next stage to further next stage.
Once I used parallel inductor between one stage to next stage and fabricated LNA , I couldn't get results at all. What is the best way to design two or three stage LNA.
Below attachments I have designed Single stage LNA, later extended same single stage LNA design to second and third stage. Please give suggestion on what best circuit or component can be connected one stage to next stage LNA design.
