Question 1.
What are Short-Channel Effects?
Show hintHide hint
Think about how channel length affects gate influence.
Question 2.
What is DIBL?
Show hintHide hint
Focus on the impact of the drain voltage.
3Question 3.
What is a major consequence of Short-Channel Effects?
- Reduced leakage current
- Increased leakage current
- No effect on performance
Show hintHide hint
Think about how scale affects the gate's control.
4Question 4.
Is Drain-Induced Barrier Lowering a phenomenon affecting the threshold voltage?
- True
- False
Show hintHide hint
Link the drain voltage to the threshold behavior.
Question 5.
Consider a MOSFET at 50 nm vs 100 nm. Calculate the expected change in leakage current due to SCE. Discuss the implications of this change.
Show hintHide hint
Use your understanding of how SCE affects current.
Question 6.
Propose a design change to mitigate DIBL in a given transistor design where DIBL influences are observed. Justify your reasoning.
Show hintHide hint
Think about architecture impacts on voltage threshold.
