Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

A common-emitter amplifier has a quiescent current of 2mA and a collector resistance of 4.7kΩ. Calculate the voltage gain.

💡 Hint: Make sure to first find the transconductance.

Challenge 2 Hard

Discuss the importance of maintaining a 'small' signal in small-signal analysis and what can go wrong if this is not adhered to.

💡 Hint: Refer back to how transistors respond to variations.
