Help in stability analysis of LNA....

Analog Design

 Hi,

 In stern's stability analysis,  I am getting both Kf and Bf1 parameter greater than one. Then what is stability level in my LNA design . What is fault in design and why this occures? I am using Cadence spectre(IC561) for rf analysis. Can anyone help me?

  • There is no such release as "IC561" so you might want to give the correct version of the environment (the IC version) and the simulator (MMSIM version, unless you're using a really old obsolete version of spectre from the IC stream) in both this and your post about sensitivity analysis.

    Andrew.
