First of all i know this is a bug. I just found it interesting, since this is an improbability in reality. A single stage amplifier with a voltage gain of 6000000 (135dB) is impossible yet there it is. The frequency response is bad and doesn't subject to the normal techniques of widening it. Also it appears to be working linearly without biasing, which is also impossible. What is more bizarre is that there isn't any LC tank circuits in which the voltage builds up. Usually at 1uV input signal, some resonance is a must.
