Question 1
A MOSFET is operating with a V_{GS} of 3V, a threshold voltage of 1V, ΞΌ_n is 400 cmΒ²/VΒ·s, and C_{ox} is 1.5 fF/ΞΌmΒ². Given W/L = 12, calculate the transconductance.
π‘ Hint: Break down the components of the equation and substitute values step-wise.
Question 2
If a designer wants to significantly increase the transconductance without changing the voltage, how can they adjust the device parameters?
π‘ Hint: Think about how these changes will affect the ratio.
