3 cards from this section. Quick, good the night before a test.
What is linearization in the context of electronic circuits?
Think about how curves can be simplified at certain points.
Define the term operating point in a BJT.
Relates to where the circuit is set before any signal is applied.
What is the purpose of linearization in electronics?
Consider what makes circuits easier to work with.
True or False: The output conductance is defined by the change in collector current concerning base-emitter voltage.
Focus on which parameters are changing in the definition.
Given that the transconductance of a BJT is 20 mS and the collector current is 10 mA, determine the change in output current if the base-emitter voltage increases by 0.1 V.
Use the transconductance formula to derive the output current change.
Describe how you would ensure a BJT remains in the active region while adjusting the operating point.
Consider the relationship between the Q-point, DC biasing, and saturation thresholds.
