Challenge Problems
Push your limits with challenges.
Question 1
A MOSFET has a transconductance of 6 mA/VΒ², and the threshold voltage is 2V. If V_gs is increased from 4V to 5V while maintaining a load resistor of 1kΞ©, calculate the output voltage change across the load.
π‘ Hint: Make sure to compute the output voltage for both states to find the difference.
Question 2
Design a small-signal model for a circuit involving two MOSFETs in a differential amplifier configuration. Consider their individual Q-points and account for their interaction.
π‘ Hint: Focus on understanding how each MOSFET impacts the circuit while linearizing them about their operating points.
