you learned in less than 10 min because of your EE class back in the 90's . if you were a beginner you wouldn't had understood that fast with Medhi

EE undergrad here, thanks for all of your videos, it's really helpful for understanding the concepts in deep.

Currently in a coarse largely focused on MOSFETs and it was just lovely learning that the BJT's equivalent of a MOSFET's saturation region is called it's active region. Then to double down on the confusion, they called the linear/triode region of a MOSFET a BJT's saturation region. Ahhh I love electrical engineering.

The simplified transistor schematics makes more sense if you view the two back to back diodes as optically coupled LEDs / photo-diodes. So every every electron that crosses the Base-Emitter diode emits a photon. These photons travel over to the Base-Emitter diode to get absorbed and each allow one electron to cross its PN-junction as reverse current. If you take this model, then the current amplification factor of the transistor inversely depends on the percentage of photons that get lost during the process (about 0.5% for a typical hfe of 200).

In college, a teacher taught us "approximate to graduate". In other words, Vbe is 0.65V usually, use nominal beta, etc. i.e. keep sight of the big picture, and not the little details. Thanks again!
