6.1.3. Practical Method of Finding Solution

Try these first

1. 1.

   What is a pull-up characteristic?

   Hint

   Think about connections to power sources.

2. 2.

   What does the iterative method do?

   Hint

   Remember how we improve guesses in steps.

3. 3.

   What does the pull-up characteristic relate to?

   • Ground connections
   • Higher voltage connections
   • Neutral connections

   Hint

   Think of which direction the current flows.

4. 4.

   Is the iterative method only applicable to linear circuits?

   • True
   • False

   Hint

   Consider the nature of complexity in circuits.

5. 5.

   Given a diode circuit, apply the iterative method to find the voltage across the diode. Use an initial guess of 0.7V.

   Hint

   Start with your guess and check the current and voltage relation.

6. 6.

   Design a small signal equivalent circuit for a diode operating at 1V with a dynamic resistance of 20Ω. Calculate its response to a small input signal.

   Hint

   Focus on the small variations from the operating point.
