hi, I've been asked to draw a piecewise linear model of a diode and state the function of each component in the model.
Am i right in thinking that this would be a diode in series with a resistor from a DC supply?
in which case i presume its silicon (doesn't say) and so has a cut in voltage of 0.7V
which creates a graph with
Id on the y axis
Vd on the x axis
and a curve that stays flat until 0.7v when it rises.
then i presume the resistor will have a large voltage drop across it as well as reducing the current.
and a silicon diode allows current to only flow in one direction
somehow though i figure this is not what the question wants me to do (its worth 6 marks) any ideas?
Thanks, Lee.
