Hello,
I am designing an LNA in the 4-8GHz range in Cadence. When I model my schematic with a direct path to ground, it is completely stable (I am checking the k-factor). However, when I add even 1 nH inductance to model an inductor, the circuit becomes unstable. Does anyone have any ideas on how I can mitigate this?
I know that in practice, typically many bondwires are used to reduce the inductance but this has proven to not be enough to fix the stability issues. Any advice would be greatly appreciated
