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
💡 Hint: Think about how saturation works.
Question 2
True or False: The gate current in a common source amplifier is significant.
- True
- False
💡 Hint: Consider the properties of the MOSFET.
