17.5.3. Triode Region Behavior

Try these first

1. 1.

   What happens to the output voltage when the input voltage exceeds the threshold voltage?

   Hint

   Think about how the MOSFET behaves when it receives enough input voltage.

2. 2.

   Define transconductance in one sentence.

   Hint

   Consider what transconductance signifies in terms of control.

3. 3.

   What does a MOSFET in the triode region resemble?

   • A howitzer
   • A variable resistor
   • A capacitor

   Hint

   Think about the linear response of a resistor.

4. 4.

   True or False: The gain for a MOSFET can be calculated using the formula -g_m * R_D.

   • True
   • False

   Hint

   Recall the components of gain.

5. 5.

   Consider a MOSFET circuit where the gate voltage fluctuates between 1V and 3V. If the threshold voltage is 2V, describe in detail the expected behavior of the MOSFET and the impact on output characteristics.

   Hint

   Think about how threshold voltage affects device state.

6. 6.

   You have a circuit with a MOSFET circuit where the output varies significantly with fluctuations in input voltage. Propose a method to stabilize the output.

   Hint

   Consider methods that use existing outputs to influence inputs.
