Im missing a concept regarding saturation, active mode of a npn transistor.
for a bjt npn to be in saturation mode the collector base junction is forward biased and the base emitter junction is forward biased.
If you look at the bjt as a diode model you see that the collector base junction diode has its cathode pointing to the Vcc of the collector and the anode pointing to the base. so current flow creates a reverse biased situation.
My question is what will ever make the collector base junction looking at it as a diode model go into a forward biased situation?
To me it always seems as if the collector base junction is always reversed biased?
Is a forward biased situation in the collector base junction caused by increasing the amount of current flowing through it regardless of the diode direction?
