There’s another problem, which I only noticed now after looking at the DC values:
Q1 has the wrong pinout!
You’ll need to go into the Q1 “Spice model…” and tick “Alternate node sequence” and enter 3 2 1.
Why? Because Q1 has C=3, B=2 and E=1. But Spice always expects that transistors have sequence CBE=123.
I attach a (now) correct simulation where Q1 is not electrically upside down. Input is 1 VAC and the DC levels are correct.
Sorry I missed that.
As you see, lots of traps when using Spice. Transistors will work when C and E are swapped, but with miserable hFE, which explains the DC offset.
Show us your final results!
PS: the reason we get different results is that I’m actually using a BC857(nexperia) Spice model for Q1. Your next sim should be identical to mine, small-signal transistors aren’t very different when used correctly…
