5.2.4. Temperature Variations

Try these first

1. 1.

   What happens to the threshold voltage of a transistor as temperature increases?

   Hint

   Think about how temperature affects the mobility of charge carriers.

2. 2.

   Explain how temperature might affect a resistor's value.

   Hint

   Consider the materials used in resistors.

3. 3.

   How does increased temperature affect the mobility of charge carriers in a semiconductor?

   • Increases mobility
   • Decreases mobility
   • No effect

   Hint

   Think about how temperature can impede movement.

4. 4.

   True or False: An increase in temperature always leads to higher resistance.

   • True
   • False

   Hint

   Consider material characteristics.

5. 5.

   Analyze a circuit's stability under varying temperatures and propose solutions for maintaining performance.

   Hint

   Consider what stabilizing features could help.

6. 6.

   Design an analog circuit aiming for specific performance metrics and describe how you'd mitigate temperature effects.

   Hint

   Think about how component selection impacts heat performance.
