Challenge Problems
Push your limits with challenges.
Question 1
A common source amplifier has a transconductance of 2 mS. If the biasing voltage is set at 3V and the threshold voltage is 1.5V, calculate the output current when the input signal voltage is 0.5V.
💡 Hint: Always plug the numbers into the transconductance equation.
Question 2
