Hi,
Iam a beginner in cadence Virtuoso...
Iam working on LNA, In prelayout simulation, S11 = S22 < -10dB; S21 = 20dB; S12 <-30dB;
In post layout Simulation,
S11 = S22 < -10dB; S21 = -10dB; s12 < -30dB
Iam getting negative gain...
Can anyone tell me what may be the reason for negative gain?? Kindly help me...
