Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

Calculate the voltage gain of a CS amplifier with g_m = 1.5mS, R_D = 10kΩ, and r_o = 5kΩ. Discuss the result.

💡 Hint: Use the parallel resistance formula to calculate R_D || r_o.

Challenge 2 Hard

If you wish to design a CS amplifier with a target gain of -15, and you have R_D = 4kΩ available, what g_m do you need?

💡 Hint: Think about the relationship between gain and transconductance.
