2 cards from this section. Quick, good the night before a test.
What happens to the minority carrier concentration in a BJT during forward bias?
Relate this to the definition of forward bias.
Define injection current in a BJT.
Think about the flow direction in forward bias.
What is the effect of forward bias on minority carrier concentration?
Think about how biasing influences carriers.
True or False: The recombination current is independent of carrier concentration.
Reflect on the relationship between availability and recombination.
Calculate the impact on collector current if the base-emitter voltage is increased from 0.7V to 0.8V while keeping the characteristics of the BJT constant.
Use the exponential relationship of current with voltage in your calculations.
In a lab experiment, the recombination current was measured to be 5 μA while the injection current was 20 μA. Determine the net effect these currents will have on the base current.
Focus on the concept of how injection and recombination balance out in the calculations.
