Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

Consider a CE amplifier that has an input resistance of 1kΩ and an output resistance of 10kΩ. If the input signal is 0.5V, calculate the output voltage considering a gain of -20.

💡 Hint: Apply the voltage gain formula.

Challenge 2 Hard

An amplifier experiences a significant temperature rise leading to failure. Discuss steps you would take to redesign to mitigate power dissipation issues.

💡 Hint: Consider material and physical changes in your design.
