Challenge Problems

Push your limits with challenges.

Question 1

Design a self-biased common emitter amplifier with specific requirements: Gain of 40 dB, lower cutoff frequency of 100 Hz, and appropriate values for R_E and R_C.

💡 Hint: Start with gain equations to find resistor values; then use the rc trap to decode capacitance.

Question 2

What would happen if you used a 1nF bypass capacitor in a circuit designed for a lower cutoff frequency of 10 Hz?

💡 Hint: Think about the impact of reactance at lower frequencies with respect to capacitor sizing.
