Question 1.
What does MOSFET stand for?
Show hintHide hint
Remember the components of its name.
Question 2.
In which operational region does the MOSFET not conduct?
Show hintHide hint
Think about the conditions under which there is no current flow.
3Question 3.
What is the primary characteristic of a MOSFET?
- Current-controlled
- Voltage-controlled
- Heat-controlled
Show hintHide hint
Consider what controls the flow of current in a MOSFET.
4Question 4.
Does a MOSFET conduct in the Cut-off region?
- True
- False
Show hintHide hint
Think about which operational states allow current flow.
Question 5.
If an E-MOSFET has a threshold voltage of 2.5V and a gate-source voltage of 5V, determine whether the device will conduct and explain your reasoning.
Show hintHide hint
Compare VGS with Vth.
Question 6.
Design a simple circuit using a MOSFET as a switch that conserves energy. Explain how you would configure the gate voltage to achieve efficient operation.
