Question 1.
What happens to the current in a MOSFET when V_GS exceeds V_th?
Show hintHide hint
Think about what 'threshold voltage' means.
Question 2.
Define channel length modulation.
Show hintHide hint
Consider how varying voltage impacts the channel length.
3Question 3.
What does channel length modulation impact?
- Only threshold voltage
- Drain-source voltage
- Drain current
Show hintHide hint
Consider how varying lengths due to voltage changes impact current.
4Question 4.
In saturation, does I_D primarily depend on V_DS?
- True
- False
Show hintHide hint
Focus on what keeps I_D constant.
Question 5.
Propose a multi-stage amplifier design which incorporates MOSFETs, taking into account the effects of channel length modulation on gain and stability.
Show hintHide hint
Integrate knowledge of varying operational conditions in MOSFETs.
Question 6.
Analyze how operational amplifiers using MOSFETs behind the scenes might design their output stage considering channel length variations.
Show hintHide hint
Think about real-world adaptability to circuit changes due to channel modulation.
