17.2. Introduction to Non-linear Circuit Analysis

Try these first

1. 1.

   What does MOSFET stand for?

   Hint

   Think about the components that make up the transistor.

2. 2.

   What are the two operating regions of a MOSFET?

   Hint

   Consider how current flows in these regions.

3. 3.

   What region allows for maximum current flow in a MOSFET?

   • Triode Region
   • Cutoff Region
   • Saturation Region

   Hint

   Think about the state of the transistor when fully 'on'.

4. 4.

   True or False: In the triode region, a MOSFET's output current is constant.

   • True
   • False

   Hint

   Consider how the MOSFET behaves in this region.

5. 5.

   Design a simple circuit using an NMOS transistor where the gain needs to be at least 10. Choose appropriate values for the gate voltage, load resistance, and verify the operating point.

   Hint

   Start with the gain formula and find suitable component values.

6. 6.

   The current flowing through a MOSFET in the triode region is 5 mA, and the output voltage is 3V. Given a load resistance of 1kΩ, calculate the necessary gate voltage to ensure saturation.

   Hint

   Always check if changes affect the region of operation.
