Question 1.
Define Thermal Voltage.
Show hintHide hint
Think about the voltage's relationship with temperature.
Question 2.
What is the purpose of temperature compensation in voltage references?
Show hintHide hint
Remember why the output needs to stay stable.
3Question 3.
What is the formula for thermal voltage?
- VT = q/kT
- VT = kT/q
- VT = kT * q
Show hintHide hint
Remember the variables involved and their relationships.
4Question 4.
Temperature compensation is primarily used to -
- True
- False
Show hintHide hint
Think about why we need stable voltage in circuits.
Question 5.
Design a voltage reference circuit using diodes and explain how you would implement temperature compensation.
Show hintHide hint
Focus on how the differing temperature responses of the diodes could be used to offset one another.
Question 6.
Evaluate the potential issues with not including temperature compensation in a voltage reference design.
Show hintHide hint
Consider scenarios where voltage readings fluctuate significantly.
