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 = 1kΞ©, calculate the necessary V_BE.
π‘ Hint: Analyze how V_BE is critical for setting your expected current.
Question 2
In a numerical example, if R_C = 4kΞ© and R_E = 1kΞ©, and V_CC = 15V, what is the voltage gain if Ξ² = 150?
π‘ Hint: Consider any thermal stability provided by the emitter resistor's presence.
