6 sample questions

Question 1.
What is the threshold voltage in a MOSFET?
Show hintHide hint
Think of it as the 'on' switch for the MOSFET.
Question 2.
Describe the saturation region for a MOSFET.
Show hintHide hint
In this region, current remains relatively constant.
3Question 3.
What does the gate voltage control in a MOSFET?
- Drain current
- Source resistance
- Gate capacitance
Show hintHide hint
Think about what the gate does when you apply voltage.
4Question 4.
True or False: The MOSFET can operate in saturation mode when the drain-source voltage is high.
- True
- False
Show hintHide hint
Recall the definition of saturation.
Question 5.
Design a simple amplifier circuit using an NMOS transistor with a target gain of 10. Specify values for K, R, and V_GS to achieve this.
Show hintHide hint
Start with choosing suitable K and calculate accordingly.
Question 6.
Given a circuit with a PMOS, if V_DD = 12V, V_GS = 4V, and R_D = 1K, calculate the output voltage and determine if the MOSFET is operating in saturation.
Show hintHide hint
Understand the conditions for saturation and use Ohm's law.
