13.1.2. Revisiting MOSFET (Contd.)

Try these first

1. 1.

   What happens when VGS is less than Vth?

   Hint

   Think about cutoff.

2. 2.

   In which region does the MOSFET operate when VGS exceeds Vth but VDS is low?

   Hint

   Recall the term 'triode'.

3. 3.

   What is the threshold voltage in a MOSFET?

   Hint

   What voltage turns the device on?

4. 4.

   True or False: In saturation, the current is directly proportional to VDS.

   • True
   • False

   Hint

   Consider the behavior of the current in saturation.

5. 5.

   Given VGS = 5V, Vth = 2V, calculate the current for VDS = 4V using saturation equation.

   Hint

   Check if saturation conditions are met.

6. 6.

   Discuss how increasing channel length affects the I-V characteristics in saturation.

   Hint

   Think about the physical implications of channel length.
