4 cards from this section. Quick, good the night before a test.
What are the two types of biasing in BJTs?
Think about how a voltage can either allow or restrict current flow.
Which terminal current in a BJT is typically the smallest?
This current supports the operation of the transistor.
What determines the collector current in a BJT?
Think about what fuels the current flowing into the collector.
True or False: The base current in a BJT is the largest terminal current.
Remember the role of the base region.
A BJT has a base current of 50 µA and a current gain (β) of 200. Calculate the collector current and discuss its significance in a circuit application.
Make sure to remember the collector current equation!
If a BJT's reverse saturation current is 1 nA and the applied reverse voltage is 10 V, discuss the effect this has on the junction operation and explain why this condition is essential in the design.
Consider how the reverse bias affects the depletion region size.
