So I am either doing something wrong in the sim or I am just not grasping the basics I guess
So I have a simple PNP with a 5 k on the emitter and 20k on the collectors.
I have an idea current source connected to the base of the pnp.
above the 5k there is a 12V voltage source.
I set the current source to 1uA and I get 250uA of current through the 20k. ok cool
then. I made it 10uA on the base and get 450uA of current through the 20k, ok also cool
I make it 100uA and I get 470uA of current through the 20k, ok makes sense starting to approach saturation apparently and im running out of gain
put 1 mA of current on the base and I get 250uA of current......... ummmmm ok now im confused???
If I am on the verge of saturation why the heck is my collector current going down????
Utter confusion instills.
Can anyone explain why this is? Thanks
