Challenge Problems
Push your limits with challenges.
Question 1
Given a BJT with g_m = 15 mS, an R_C load of 2 kΩ, calculate the voltage gain and explain its significance.
💡 Hint: Remember what a negative gain indicates in terms of phase.
Question 2
If a small signal input causes a current increase that exceeds predicted values due to Q-point shifts, discuss the implications on design choices.
💡 Hint: Think about how variations can lead to misbehavior in amplifiers.
