Challenge Problems
Push your limits with challenges.
Question 1
Calculate the sensitivity of collector current to changes in beta for a fixed bias configuration with R_E = 0 and given values of R_B and V_BB.
π‘ Hint: Think about the role of feedback and resistance ratios.
Question 2
You have a CE amplifier with a self-bias configuration. If the emitter resistor is too large compared to base resistance, analyze how this affects the operational stability.
π‘ Hint: Consider how resistors in series and feedback networks work.
