A MOSFET has a threshold voltage (Vth) of 0.7 V, and operates with ID of 10 mA at VGS = 3 V. Calculate its transconductance and its output current for a small signal VGS = 0.01 V.
💡 Hint: Use the transconductance formula and plug in the values carefully.
Explain how the small signal model assists in determining the bandwidth of a MOSFET amplifier, given you're varying Vgs to analyze performance.
