2 cards from this section. Quick, good the night before a test.
What is voltage gain?
Think of the basic formula involving input and output.
What is the purpose of the emitter resistor (R_E)?
Consider what happens to the gain if this resistor is too high.
What factor degrades the gain in a CE amplifier?
Consider the role of stabilization vs. gain.
True or False: The emitter resistor helps to increase the gain in a CE amplifier.
Remember its effect from the voltage gain formula.
A CE amplifier has R_E = 1kΩ and R_C = 4kΩ, calculate the estimated voltage gain.
Consider g_m values in relation to the transistor specifications.
Design a circuit with a minimum cutoff frequency of 20 Hz, detailing the choice for R_E and capacitor.
Use the known relationship of RC in determining frequency responses.
