Try these first
- 1.
What occurs in the cut-off region?
Hint
Think of a switch.
- 2.
When does an E-MOSFET act like a variable resistor?
Hint
Remember the voltage relationship.
- 3.
What happens in the Cut-off region?
- No current flows
- It acts as a variable resistor
- Current is constant
Hint
Think about what a switch does.
- 4.
In which region does the MOSFET behave like a variable resistor?
- Cut-off Region
- Triode Region
- Saturation Region
Hint
Focus on how VGS influences the current.
- 5.
Design a circuit using an E-MOSFET and discuss how to operate it in each of the three regions.
Hint
Focus on the role of Vth when designing.
- 6.
Explain how the performance characteristics of an E-MOSFET might change when operated closely between the Triode and Saturation regions.
Hint
Consider the implications of variable resistance here.
