1. 1.

   What does MOSFET stand for?

   Hint

   Think about the type of transistor we're discussing.

2. 2.

   What region of operation allows a MOSFET to conduct maximum current?

   Hint

   This is a key term we discussed.

3. 3.

   What is the primary advantage of MOSFETs over BJTs?

   • Higher current control
   • Higher input impedance
   • Simplicity in biasing

   Hint

   Consider the input characteristics we've discussed.

4. 4.

   True or False: In saturation, I_DS is highly dependent on V_DS.

   • True
   • False

   Hint

   Recall our discussions on saturation conditions.

5. 5.

   If a common source MOSFET has a V_GS of 3V, V_th of 1V, and K of 2 mA/V², calculate the I_DS. Also, explain how I_DS changes with a higher V_DS.

   Hint

   Consider the impact of transistor operation regions.

6. 6.

   Given a circuit with a drain resistor of 1kΩ and an I_DS of 3 mA, find the V_DS and discuss how changes in R_D affect output voltage swing.

   Hint

   Think about the trade-offs involving gain and distortion.
