Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

If a BJT amplifier circuit is designed for an input signal of 50 mV p-p and the calculated Q-point leads to a high distortion, how would you adjust your biasing to reduce distortion?

💡 Hint: Think about how changing the resistive elements in your biasing can affect performance.

Challenge 2 Hard

You measure your installed Q-point and find I_C higher than expected. What steps do you take to troubleshoot this situation?

💡 Hint: Investigate all parts of the circuit to isolate the cause.
