Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

A differential amplifier has a base bias of 12V with a BJT configured. If the base resistor is 570 kΩ, calculate the emitter current if V_BE = 0.6V.

💡 Hint: Use Ohm's law to find current from voltage and resistance.

Challenge 2 Hard

Discuss the impact of a weak common mode rejection ratio in a sensitive amplifier application. What strategies would you employ to mitigate common mode signals?

💡 Hint: Think of ways you can enhance signal clarity in your designs.
