I know this question has been asked a lot of times and there are a lot of tutorials but please bare with me for one second. I understand the basic concept but based on my simulated results, one thing is not matching my expectation. Please see circuit below.
I expect that when I increase the base voltage very high, the collector voltage will decrease to 0, as it does. But why doesn't this put the transistor into cutoff/saturation? Why doesn't the current decrease to zero? No matter what Vbe is, all Vce curves go to zero.
Here is a link to the VCE curve: https://www.st-andrews.ac.uk/~www_pa/Scots_Guide/info/comp/active/BiPolar/bpcur.html
[EDIT] Also, note that the 2N3904 has a saturation collector-emitter voltage of 0.2. So really, as soon as the voltage decreases below 0.2, it should decrease.
