* Diode SPICE subcircuit
|
|
* Generic diode model with proper SPICE parameters
|
|
*
|
|
* Parameters:
|
|
* IS - Saturation current (controls forward voltage)
|
|
* N - Ideality factor (1.0 for ideal diode, higher for real diodes)
|
|
* RS - Series resistance
|
|
* CJO - Junction capacitance (optional)
|
|
*
|
|
* Nodes:
|
|
* 1 - Anode
|
|
* 2 - Cathode
|
|
|
|
* Standard silicon diode - ~0.7V forward voltage
|
