Question 1.
What is channel-length modulation?
Show hintHide hint
Think about how voltage can affect the current paths in a transistor.
Question 2.
What does λ represent in the context of MOSFETs?
Show hintHide hint
It indicates the influence of the length of the conductive channel on the current.
3Question 3.
What is the effect of channel-length modulation on drain current?
- It decreases the drain current
- It has no effect
- It increases the drain current
- It stops the current
Show hintHide hint
Consider how applied voltage changes the channel properties.
4Question 4.
True or False: Channel-length modulation is significant in short-channel devices.
- True
- False
Show hintHide hint
Think about how channel length affects modulation effects.
Question 5.
If a MOSFET has a channel length of 100 nm and a drain-source voltage of 5V, explain how channel-length modulation might influence its performance compared to a 500 nm long channel under the same conditions.
Show hintHide hint
Consider the impact of length on the modulation factor.
Question 6.
Demonstrate how ignoring channel-length modulation in a short-channel MOSFET could lead to circuit design failures.
Show hintHide hint
Think about issues related to current predictions and material performance.
