3 cards from this section. Quick, good the night before a test.
What does it mean when we say a junction is forward-biased?
Think about which side is 'charged' more positively.
Name the two types of carriers in a BJT.
One type is present in p-type material while the other is in n-type material.
Which condition allows current to flow from the emitter to the base in a BJT?
Think about how the positive charge affects current flow.
True or False: Minority carriers are present in larger concentrations than majority carriers in a BJT.
Think about the definitions of majority vs. minority carriers.
If a BJT's base-emitter voltage is increased from 0.2V to 0.7V, describe the change in current flow in the junction.
Recall how voltage and current are related in a diode.
A BJT is operating at a temperature of 60°C and the intrinsic carrier concentration doubles. How does this impact the minority carrier concentration?
Think about the impact of temperature on carrier dynamics.
