6.1.5. Linearization of the Circuit

Try these first

1. 1.

   What defines a non-linear circuit?

   Hint

   Think about how the diode behaves with voltage changes.

2. 2.

   Describe a piece-wise linear model.

   Hint

   Consider how we simplify curves into straight lines.

3. 3.

   What is a non-linear circuit?

   • Does not follow Ohm's Law
   • Follows Ohm's Law
   • Is a series circuit

   Hint

   Think about diodes and their current-voltage behavior.

4. 4.

   True or False: A piece-wise linear model can be used for any voltage condition.

   • True
   • False

   Hint

   Consider the linear segments created based on voltage ranges.

5. 5.

   Given a complex diode circuit, derive its piece-wise model and determine the output for various input signals including AC.

   Hint

   Identify the operating regions carefully.

6. 6.

   Analyze a small signal equivalent circuit of a transistor at a quiescent point and reconfigure it for a different point while maintaining accuracy.

   Hint

   Reapply linearization methods to the new DC operating point.
