13.3.1. Example Using n-MOS Transistor

Try these first

1. 1.

   What is the threshold voltage (V_th)?

   Hint

   It defines when the transistor turns on.

2. 2.

   Name the two main operational regions of an n-MOS transistor.

   Hint

   Think about how the current behaves.

3. 3.

   What is the main function of an n-MOS transistor?

   • Amplification
   • Switching
   • Both
   • None

   Hint

   Consider its applications in circuits.

4. 4.

   True or False: The current in saturation region depends on V_DS.

   • True
   • False

   Hint

   Think about how saturation affects current flow.

5. 5.

   Given a MOSFET with K = 0.5 mA/V², V_th = 1V, and V_GS = 4V, calculate I_DS for both the triode and saturation regions when V_DS = 1V and V_DS = 3V respectively.

   Hint

   Check the region for each condition; use respective equations!

6. 6.

   Explain the effect of reducing V_GS on the n-MOS transistor operational point.

   Hint

   Think about how V_GS relates to current flow.
