Challenge Problems

Push your limits with challenges.

Question 1

Analyze a differential amplifier circuit configured with two BJTs, calculating the input common mode range and the expected differential voltage gain given specific resistor values.

💡 Hint: Utilize small signal analysis techniques covered in class for detailed steps.

Question 2

Given an array of signals input to a differential amplifier, determine how the output responds in terms of gain and stability when varying the common mode signal levels.

💡 Hint: Focus on the idea that varying the inputs changes how the circuit handles the common signals.
