What is the formula for calculating input resistance in a CE amplifier?
Think about how the emitter resistor affects input resistance.
Why is having a high input resistance important?
Consider the signal's journey into an amplifier.
What role does the emitter resistor (R_E) play in a CE amplifier?
Think about the implications of resistance in biasing circuits.
True or False: The output resistance is determined solely by the collector resistor (R_C).
Consider the components that interact at the output.
Design a CE amplifier with R_E = 200Ω providing a gain of at least 50. Considering R_C needs to be much higher than R_E, suggest values while maintaining stability.
Remember that increasing R_C directly boosts gain while ensuring R_E supports stability against variations.
Analyze how introducing a capacitor across R_E would change the amplifier's input and output characteristics.
Consider the frequency-dependent behavior of capacitors in AC circuits.
