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.
