Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

Design a simple common emitter amplifier circuit with given parameters. Calculate the lower and upper cutoff frequencies based on given capacitance and resistance.

💡 Hint: Follow the RC formula!

Challenge 2 Hard

You have an amplifier where lowering the capacitance at the input increases the lower cutoff frequency significantly. Discuss how this affects the amplifier’s ability to amplify low-frequency signals.

💡 Hint: Consider the relationship between capacitance and frequency.
