6 sample questions

Question 1.
What are the two types of power consumption in CMOS circuits?
Show hintHide hint
Think about when power is consumed: Is it during switching or not?
Question 2.
What does leakage current refer to?
Show hintHide hint
It happens even when the device is not active.
3Question 3.
What is the main characteristic of static power in CMOS circuits?
- High when the circuit is in active state
- Minimal when transistors are off
- Maximized by leakage
Show hintHide hint
Think about the circuit's state when it is not operating.
4Question 4.
Dynamic power consumption is affected by which of the following factors?
- True
- False
Show hintHide hint
Recall the factors impacting dynamic power you learned.
Question 5.
If a CMOS circuit has a supply voltage of 1.8 V and operates at a frequency of 500 kHz with a load capacitance of 20 nF and a switching activity of 0.3, calculate the dynamic power consumption.
Show hintHide hint
Make sure you're using the right units and plugging in the values correctly.
Question 6.
Describe strategies to significantly reduce both static and dynamic power in modern CMOS designs.
Show hintHide hint
Think about innovations in CMOS technology and design methods.
