Challenge Problems
Push your limits with advanced challenges
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.
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.
