2 cards from this section. Quick, good the night before a test.
Define voltage gain in your own words.
Think about how much the signal is amplified by the amplifier.
What is the role of the base current in a BJT circuit?
Think of how the base current affects transistor action.
What is the primary advantage of using an active load in amplifiers?
Think about the relationship between impedance and gain.
True or False: The output resistance of an active load configuration is generally higher than that of a passive load.
Consider the properties of transistors versus passive loads.
If the beta of a transistor in an active load configuration is increased, how would that affect the output current?
Explore the relationship between beta, base current, and collector current.
Derive the equation for the cutoff frequency and explain what factors influence it in the context of active loads.
Recall how resistance and capacitance interact in RC circuits.
