Challenge Problems
Push your limits with challenges.
Question 1
A common source amplifier has a transconductance of 1.5mS and is biased at 2V. For an input signal of 4V, find the output current when the threshold voltage is 1.5V.
💡 Hint: Use the small signal current equation discussed.
Question 2
Design a common source amplifier circuit using an N-channel MOSFET to achieve a voltage gain of 10 while ensuring the MOSFET operates in the saturation region. Specify appropriate values for resistances.
💡 Hint: Consider the resistor values that could yield a gain of 10 while respecting DC bias calculations.
