Why do I get a negative Re(Zin) while performing SP in ADS?
the real part of Zin I got is -52.450@1GHz, -22.039@2GHz.
I'm wondering why does this happen.
Best Regards.
Perhaps the ckt is not unconditionally stable.
Why does that happen? So that microwave engineers can get paid! It is a good thing.
Hi,
I think you have biasing problem.
check your dc bias poins.
your transistors aren't in active region.
Regards
Hi,
I surely have checked the bias conditions, they're definitely in the active regions.
I apprecitate if you have a shot at this circuit with SP simulation.
Thank you.
I agree with g579: it's the stability problem.
