Question 1

What condition must V_D satisfy to keep the MOSFET in saturation?

  • V_D < V_GS - V_th
  • V_D = V_th
  • V_D > V_GS - V_th

πŸ’‘ Hint: Think about how saturation works.

Question 2

True or False: The gate current in a common source amplifier is significant.

  • True
  • False

πŸ’‘ Hint: Consider the properties of the MOSFET.
