Challenge Problems
Push your limits with challenges.
Question 1
Design a self-biased CE amplifier with an operating point of 10mA. Given V_BB = 10V and R_E = 1kΩ, calculate the necessary V_BE.
💡 Hint: Analyze how V_BE is critical for setting your expected current.
Question 2
In a numerical example, if R_C = 4kΩ and R_E = 1kΩ, and V_CC = 15V, what is the voltage gain if β = 150?
💡 Hint: Consider any thermal stability provided by the emitter resistor's presence.
