4.4. Design Considerations for CMOS Voltage References

Try these first

1. 1.

   What is a common output voltage for CMOS voltage references?

   Hint

   Think of standard bandgap references.

2. 2.

   What does temperature coefficient measure?

   Hint

   Focus on temperature changes.

3. 3.

   What is the ideal temperature coefficient of a voltage reference?

   • High
   • Low
   • Zero

   Hint

   Think about desired stability.

4. 4.

   True or False: Low power consumption is less important for battery-powered devices.

   • True
   • False

   Hint

   Consider the implications of energy use.

5. 5.

   Design a voltage reference circuit considering minimum temperature coefficient, explaining the components and configurations you would use.

   Hint

   Think about balancing factors.

6. 6.

   Assess how noise affects an ADC performance, proposing methods to mitigate this impact in voltage reference design.

   Hint

   Consider where noise can influence your signals.
