Challenge Problems

Push your limits with challenges.

Question 1

Design a common gate amplifier with a drain current of 2mA and calculate the required biasing resistances if the drain voltage is set to 10V.

💡 Hint: Use Ohm’s Law in conjunction with the gain equations to find necessary resistances.

Question 2

If the current gain of your constructed common gate amplifier is measured at 0.95 and the source resistance is increased to 20kΩ, analyze the possible effects on signal fidelity.

💡 Hint: Consider how variations in source resistance can affect total gain and input impacts.
