Based on the equivalent circuit model of a two-port optical receiver front-end, the relationship between the equivalent input noise current spectraldensity and the noise figure is analyzed.

With same input signal to excite two systems, the results show that the power spectraldensity of the output can't identify non-minimum phase signal.
