2 cards from this section. Quick, good the night before a test.
What does transconductance (g_m) measure?
Think about how the output current reacts to changes in input voltage.
Define the base-emitter resistance in a BJT.
Consider what resistance affects the input current.
What is the purpose of linearizing non-linear circuits?
Think of how we make circuits easier to work with.
True or False: The value of g_m is constant regardless of the operating point.
Consider how changing bias points can affect circuit parameters.
For a given BJT with a collector current of 1 mA and operating at room temperature, design a small signal equivalent circuit. Determine g_m, r_π, and draw the equivalent circuit.
Use the equations discussed for g_m and r_π to summarize your parameters.
Discuss the consequences of exceeding the linear operating region of a BJT in a circuit. Provide examples of distortion types that may arise.
Think about how non-linear effects might alter your signals.
