3 cards from this section. Quick, good the night before a test.
What is the lower cutoff frequency?
Think about the implications of gain on frequency.
Define a coupling capacitor.
Consider its role in amplifier circuits.
What is the impact of increasing the emitter resistor?
Think about the voltage gain formula discussed.
True or False: Coupling capacitors can only be used with DC signals.
Review their purpose in amplifier circuits.
Design an amplifier circuit with given specifications targeting a specific lower cutoff frequency. Discuss how you would select component values and justify your decisions regarding R_E and C values.
Use the formula for cutoff frequency to link R and C.
You have an amplifier circuit where increasing R_E from 1kΩ to 10kΩ dramatically reduced gain. Provide a mathematical analysis of this scenario, including the implications of stability and what design considerations you recommend.
Reflect on how changes in R_E affect the gain as described in class.
