ABSTRACT
A component may often be modeled in different ways. A diode, for example, is normally modeled as a current source controlled by its own voltage such that the model can be linearized into a
dynamic conductor
in parallel with a current source during the iterative process of finding the bias point of the diode. The diode may also be modeled as (1) a voltage source controlled by its own current (a dynamic resistor in series with a voltage source); (2) a
static conductor
being a function of the voltage across the
diode; or (3) a static resistor being a function of the current through the diode. Note that in the case where a small signal model is wanted, for frequency analysis, only the dynamic model is appropriate.
