Question 1

What is the effect of increasing the channel length (L) on the drain-source current (I_DS)?

  • I_DS increases
  • I_DS decreases
  • I_DS remains constant

💡 Hint: Consider how longer paths affect current flow.

Question 2

True or False: The drain-source current is influenced only by the gate-source voltage.

  • True
  • False

💡 Hint: Think about the factors affecting conductivity.

Challenge Problems

Push your limits with challenges.

Question 1

A MOSFET has W = 5 μm, L = 2 μm, with V_GS = 7 V and a V_th = 3 V. Calculate the current contribution if those conditions result in a channel operating short.

💡 Hint: Consider whether the MOSFET is in the triode or saturation region.

Question 2

Explain the significance of designing a MOSFET to achieve a specific I_DS when connecting to a load. What factors will influence this design?

💡 Hint: Reflect on how real-world applications require tailored designs for current versus the device specifications.
