6 sample questions

Question 1.
What happens to the output of a CMOS inverter when the input is high?
Show hintHide hint
Think about the function of the NMOS transistor.
Question 2.
True or False: The PMOS transistor conducts when the input of a CMOS inverter is high.
Show hintHide hint
Recall how PMOS and NMOS operate in the inverter.
3Question 3.
What is the output of a CMOS inverter when the input is low?
- High
- Low
- Undefined
Show hintHide hint
Think about the function of the PMOS transistor.
4Question 4.
True or False: CMOS inverters consume a lot of static power.
- True
- False
Show hintHide hint
Consider the behavior of transistors when they are off.
Question 5.
Design a CMOS inverter that can operate efficiently with a power supply of 3.3V and withstand a load capacitance of 10pF. Discuss your transistor sizing and how this influences power and speed.
Show hintHide hint
Consider the trade-offs with increased transistor sizes versus power consumption.
Question 6.
Given a switching frequency of 1 GHz and capacitance of 20pF, calculate the dynamic power consumption of the CMOS inverter. How does this compare to its static consumption in typical usage?
Show hintHide hint
Recall the formula and consider static contribution as minimal if inactive.
