13.4. Summary

Try these first

1. 1.

   What happens in the cutoff region of a MOSFET?

   Hint

   Think about the condition of VGS.

2. 2.

   Define the triode region of a MOSFET.

   Hint

   Consider how current behaves with increasing voltage.

3. 3.

   What is the cutoff region of a MOSFET?

   • True
   • False

   Hint

   Think about what conditions are present for the transistor to be off.

4. 4.

   In the saturation region, current continues to increase linearly with VDS.

   • True
   • False

   Hint

   Reference the saturation condition and current behavior.

5. 5.

   A p-MOSFET has VGS of -2.5V and Vth of -1.5V. If VDS is -2V, calculate the drain current assuming saturation.

   Hint

   Ensure the device's conditions align with saturation requirements.

6. 6.

   Consider an n-MOSFET with K=1 mA/V², VGS=3V, and Vth=1V. If VDS is varied, analyse when the device transitions from triode to saturation?

   Hint

   Check relationships between input voltages to determine conditions.
