Ideal diode
Electrical/Analog/Ideal
This is an ideal switch which is
* open, if it is reversed biased (voltage drop less than 0)
* closed, if it is conducting (current > 0).
Note, there are circuits, where this ideal description with zero resistance and zero cinductance is not possible. In order to prevent singularities during switching, the opened diode has a small conductance Gon and the closed diode has a low resistance Roff which is default.
The parameter Vknee which is the forward threshold voltage, allows to displace the knee point along the Gon-characteristic.
