Challenge Problems

Push your limits with challenges.

Question 1

Design a common collector amplifier that maintains a voltage gain close to 1 while providing an input impedance greater than 10 MΩ. Calculate the necessary values for base voltage, emitter voltage, and collector current using given parameters.

💡 Hint: Begin with biasing conditions needed for your design.

Question 2

Given a setup with a load capacitance of 100 pF and a source resistance of 100 kΩ, analyze the impact on the upper cutoff frequency and suggest ways to optimize the design.

💡 Hint: Remember how capacitance and resistance interact at high frequencies.
