Challenge Problems
Push your limits with challenges.
Question 1
A differential amplifier has a transconductance gm of 4mS and a collector resistance Rc of 1.5k ohms. What is its differential mode gain? How would changing the collector resistance affect the output?
💡 Hint: Remember how resistance affects the gain calculations directly.
Question 2
Given a scenario where a common mode signal is around 1V while the differential signal is 0.5V, analyze the performance of a differential amplifier with significant common mode gain.
💡 Hint: Consider the implications of high common mode gain affecting overall signal clarity.
