Challenge Problems
Push your limits with challenges.
Question 1
A MOSFET with a W/L ratio of 5, $ΞΌ_n$ of 500 cmΒ²/VΒ·s, and $C_{ox}$ of 10^-6 F/mΒ² operates at $V_{GS} = 1V$ and $V_{th} = 0.5V$. Calculate $I_D$ when $V_{DS} = 0.2V$.
π‘ Hint: Substitute the values carefully and watch for unit conversions.
Question 2
Evaluate how increasing $V_{GS}$ beyond the threshold impacts the current in the saturation region when $V_{DS}$ is fixed.
π‘ Hint: Confirm how each term in the saturation equation reacts to changes in V_{GS}.
