What happens to current in a p-n junction during forward bias?
Think about the direction of voltage applied.
Define beta (β) in the context of BJTs.
It is a measure of amplification in a BJT.
What is the main purpose of a BJT?
Think about the role of small current in controlling larger currents.
In a p-n junction under reverse bias, the current is minimal.
Recall the property of reverse bias in semiconductors.
If you have a BJT where V_BE is 0.7V and it results in a collector current of 5mA, what is the base current if β is 100?
Recall the formula relating collector and base currents.
Given a BJT with a base width of 0.2 μm and D_p = 0.36 μm²/s for holes, calculate how a change in base width affects the recombination of carriers in the base.
Think about how base width and carrier longevity relate.
