Hello all,
I'm attempting to simulate the behavior of a general Darlington pair using LTspice. Each time I run my simulation as a steady state circuit, it appears that current is flowing from ground through the emitter to the voltage source that is placed on the collector. I'm led to believe this due to positive voltage values from the simulation output.
There may be some applications were that is possible, however LTspice uses conventional current flows. That said, based on my circuit the described behavior should not be possible. I have had situations where accidentally rotated resistors will read current flow as a negative value due to orientation issues. Is this one of those situations or is am I missing something conceptually?
I am a curious novice with circuits so please take it easy on me. I will attach an screen shot containing my circuit and the simulation output. Note that I did not change any of the Darlington pairs' settings. It is setup as an NPN Bipolar Transistor. I actually do not know how to customize a transistor to reflect desired beta gains or values...(I'm not sure how there parameters are typically referenced).
Thank you.
