Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

Given a simulated ID-VGS curve, describe how you would identify Vt both visually and through extrapolation. Include potential errors.

💡 Hint: Focus on the curve's initial behavior.

Challenge 2 Hard

Propose a method to determine the impact of varying VDS on the ID-VGS characteristics you've simulated. What would you expect to happen?

💡 Hint: Consider how each parameter influences current flow.
