Challenge Problems

Push your limits with challenges.

Question 1

A CE amplifier has R_C = 10kΩ, and an emitter resistor R_E = 1kΩ that is not bypassed. If g_m = 40mS, calculate the voltage gain A_v.

💡 Hint: How do you determine resistance in parallel?

Question 2

Design a CE amplifier to achieve a specific gain 80 0. What parameters would you adjust, and what is the expected input resistance?

💡 Hint: Remember how gain relates to input and output resistances!
