Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

Given a common collector amplifier with a known input resistance of 100 kΩ and an output load of 50 kΩ, calculate the expected output voltage when a 1 V input signal is applied.

💡 Hint: Consider how voltage divides between parallel resistances.

Challenge 2 Hard

A MOSFET common drain amplifier has a transconductance of 2 mS. Calculate the output current if the gate voltage changes by 1 V.

💡 Hint: This uses the basic relationship with transconductance.
