6.3. Piece Wise Linear Model

Try these first

1. 1.

   Define what the piecewise linear model simplifies in electronic circuits.

   Hint

   Think about how complex curves can be simplified to straight lines.

2. 2.

   What is Vγ in the context of a diode?

   Hint

   Consider the typical voltage drop when a diode is forward biased.

3. 3.

   What is a piecewise linear model used for?

   • Estimating analog signal frequency
   • Simplifying analysis of nonlinear circuits
   • Designing digital circuits

   Hint

   Think about the situation in which you would need a simplified version of a curve.

4. 4.

   True or False: The dynamic resistance in the on-state of a diode can be modeled as zero.

   • True
   • False

   Hint

   Consider whether any resistance is truly zero in practical circuits.

5. 5.

   Calculate the output voltage for a circuit using a piecewise linear model where input voltage varies from 0 to 10V.

   Hint

   Chart the change in current and deduce the output at each segment based on Vγ.

6. 6.

   Analyze and describe the effect of introducing a load resistor in parallel with a diode modeled by a piecewise linear approach.

   Hint

   Consider how adding another path may change the traditional current calculations.
