Question 1.
What is the threshold voltage (Vth) for a given MOSFET if VGS is 3V and ID is measurable?
Show hintHide hint
Remember that Vth sets the minimum gate-to-source voltage for conduction.
Question 2.
Identify the region of operation for a MOSFET with VGS = 3V and Vth = 1V.
Show hintHide hint
Check if VGS exceeds Vth.
3Question 3.
What happens to ID when VGS significantly exceeds Vth in n-MOS?
- ID increases linearly
- ID becomes zero
- ID remains constant
Show hintHide hint
Visualize the I-V curve responding to VGS.
4Question 4.
True or False: The threshold voltage for p-MOS is always a positive value.
- True
- False
Show hintHide hint
Think about how polarity works in different devices.
Question 5.
Design a circuit using an n-MOSFET that can operate in both saturation and triode while changing inputs. Calculate the expected ID values at each state based on example conditions.
Show hintHide hint
Ensure that VGS exceeds Vth and analyze how VDS influences ID.
Question 6.
Compare and contrast a circuit that employs both n-MOS and p-MOS transistors. Create simulations to observe how each device's I-V characteristics affect overall current flow.
Show hintHide hint
Visual comparisons can highlight the importance of polarity in MOSFET behavior.
