Challenge Problems
Push your limits with challenges.
Question 1
A common source amplifier has a threshold voltage of 1V and a gate voltage of 4V. If the output resistance is 2 kΩ and gm is 5 mA/V, calculate the voltage gain and the current flowing through the device.
💡 Hint: Remember, the voltage gain relies on the relationship with gm and resistance.
Question 2
In a cascading arrangement, calculate the total voltage gain if the first stage common source has a gain of 10 and the following common drain stage has an approximate gain of 1. What is the overall voltage gain?
💡 Hint: Cascading gains multiply!
