* LED SPICE subcircuit
|
|
* LED model based on diode with color-specific forward voltages
|
|
*
|
|
* The forward voltage is controlled by the IS (saturation current) parameter
|
|
* Lower IS values result in higher forward voltages
|
|
* Typical LED has N=2.0 (higher than regular diode)
|
|
*
|
|
* Nodes:
|
|
* 1 - Anode
|
|
* 2 - Cathode
|
|
|
|
* Red LED - ~1.8V forward voltage
