Challenge Problems
Push your limits with advanced challenges
Given a Common Emitter Amplifier with R_C = 10kΩ, g_m = 0.02 S, and R_E = 1kΩ, calculate the voltage gain. Discuss if the gain would be acceptable if R_E were increased.
💡 Hint: Use the gain formula and substitute values for full calculations.
Analyze the input resistance for a Common Emitter Amplifier with R_BB = 100kΩ, β = 50, r = 150Ω, and R_E = 200Ω. What would happen if R_E were removed?
💡 Hint: Focus on parallel resistance calculation including the base resistance.
