A n-MOSFET has a threshold voltage of 1.5V. What would happen to the current if VGS is set to 1.2V? Illustrate this behavior using an I-V curve.
💡 Hint: Plot points on a graph to illustrate the current remaining at zero until sufficient voltage is applied.
Given an n-MOSFET with Vth=1V, calculate the drain current if VGS=3V and VDS=1V. What region of operation does this MOSFET fall into?
💡 Hint: Review the equations for the triode operation and plug in your values.
