2 cards from this section. Quick, good the night before a test.
What is the role of biasing in a BJT circuit?
Think about how setting a voltage can control the current flow.
Define the term 'I-V characteristic'.
Consider how current is affected by voltage changes.
What is the typical effect of increasing V_BE on I_C in a BJT?
Think about the exponential relationship between V_BE and current.
True or False: A BJT must always operate at V_BE of exactly 0.7V to be functional.
Consider the range of operating conditions allowed for BJTs.
Design a BJT amplifier circuit with given parameters (V_BE = 0.7V, β = 120, I_B = 50µA). Calculate I_C and discuss the implications of your findings.
Keep in mind how the values of β can impact amplification.
Explain the transition from active region to saturation in a BJT and how to recognize when this occurs in a circuit.
Think about what saturation means in terms of transistor function.
