Understanding Diode I-V Characteristics and Curve Tracing with MultiSim

In conclusion, once you obtain the solution regarding a diode's function, consider these conceptual questions: Does your answer physically make sense based on diode behavior? Can you simulate the diode’s current-voltage (I-V) characteristics using MultiSim? A device known as a curve tracer can help visualize these I-V plots. You can validate your findings in MultiSim; however, it's essential to have a solid understanding of circuit interpretation. If the diode's I-V plot isn't straightforward, circuit tricks may be required, which are beyond this class's scope. For further reading, explore "Hysteresis in Electronic Circuits" by Chua and Kennedy.

  1. In conclusion, once you obtain the solution, ask yourself some conceptual • questions: • Since you know how a diode works (allows current to flow in only direction etc.), does your answer make physical sense? • Can you obtain the DP plot via simulation using MultiSim? • Turns out that there is a device called a curvetracer that draws I-V (DP) plots. So, you can* check your answer in MultiSim (as with any simulation, you should understand what you are doing to interpret the results). • I have posted a MultiSim project file that verifies our solution. • *If the DP plot is not a function, then you need to play some circuit tricks to obtain the DP plot, this is • beyond the scope of this class. If you are interested, read: • Hysteresis in electronic circuits: A circuit theorist's perspective. Chua, L. O. and Kennedy, M.P. • Int. Journal Of Circuit. Th. And Appl. 19 (1991), pp. 471-515.
