2 cards from this section. Quick, good the night before a test.
What are the three regions of a BJT?
Think about the structure of the transistor.
What type of biasing is present at the base-emitter junction in active mode?
Remember how we discussed biasing in class.
What is the role of the emitter in a BJT?
Consider what happens at the junction.
The I-V characteristic of a BJT is typically a ____ function of voltage.
Think about how the current behaves with voltage.
Given an n-p-n BJT with a forward-bias voltage of 0.7V across the base-emitter junction and a reverse-bias of 5V across the base-collector junction, calculate the expected collector current assuming β = 100 and base current of 20 µA.
Consider how the collector current amplifies the base current.
Why would decreasing the base width of a BJT affect the collector current? Provide a detailed explanation.
Think about how the base influences the behavior of electrons crossing into the collector.
