A MOSFET is operating with a V_{GS} of 3V, a threshold voltage of 1V, μ_n is 400 cm²/V·s, and C_{ox} is 1.5 fF/μm². Given W/L = 12, calculate the transconductance.
💡 Hint: Break down the components of the equation and substitute values step-wise.
If a designer wants to significantly increase the transconductance without changing the voltage, how can they adjust the device parameters?
💡 Hint: Think about how these changes will affect the ratio.
