Hi,
I have experienced the same problem with the Noise Figure analysis. I am using Student Edition 14.2.0. Our lab assignment is a simple inverting op-amp circuit. The results of the Noise Figure are negative, and they are exactly the (negative) of the gain for a given frequency. I expected the noise figure to be 20log(SNR in/SNR out), but instead they are -20log(Rf/R g).
