Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

Given a MOSFET with dimensions W=8μm, L=2μm, VGS=5V, Vth=1V, and VDS=4V. Determine the current flowing through the device under the assumptions of ideal behavior.

💡 Hint: Set up your K based on (W/L) and input your voltage values correctly.

Challenge 2 Hard

If you increase the drain voltage VDS while keeping all other parameters constant in a circuit where the current is in saturation, what would be the physical implication in the MOSFET's operation?

💡 Hint: Remember, saturation limits the effect of higher VDS on current.
