Challenge Problems
Push your limits with challenges.
Question 1
Calculate the necessary biasing resistances if you want to produce a base voltage of 8V from a 12V source using a voltage divider with R_A and R_B.
💡 Hint: Use the voltage divider rule: V_base = V_dd * (R_B / (R_A + R_B)).
Question 2
Given a common base amplifier is experiencing signal distortion at the output, what might be causing it and how can you rectify it?
💡 Hint: Look into the exponential characteristics of the transistor and ensure the biasing matches the expected signal levels.
