2 cards from this section. Quick, good the night before a test.
What happens to capacitors in small signal equivalent circuits?
Think about how they behave in AC analysis.
What is the equation for collector current I_C in terms of base current I_B?
Remember the relationship between base and collector currents.
What does the small signal equivalent circuit treat DC values as?
Consider the overall purpose of small signal analysis.
True or False: V_out can become positive if I_C is negative.
Think about how current flows in the circuit.
Given a CE amplifier with R_C = 2kΩ, beta = 120, and I_B = 20µA, calculate the maximum possible V_out.
Remember to consider the direction of current flow for voltage polarity.
Discuss how a change in temperature influences beta and subsequently the signal output in a real amplifier.
Consider how `beta` affects both the input and output currents.
