as complete as the semiconductor diode model is in LTspice, there are times when you need a simple “idealized diode” model to quickly simulate, for example, an active load, a current source or a current limiting

In practice, the values of XTI and EG need tuning to model the exact behavior of a particular diode. Some manufacturers quote these tuned values in a SPICE Netlist, and you can read off the appropriate values. Otherwise, you can determine improved estimates for EG by using a datasheet-defin...
Where a parameter has an indicated default (as part of the SPICE model definition), that default will be used if no value is specifically entered. The default should be applicable to most simulations. Generally you do not need to change this value. ...
The focus is on the model structure and calculations of the necessary parameters. An example is given to illustrate the simulation result by using the SPICE diode model and the macro model approaches.doi:10.1080/00207219108925477WONG, SILPHY
The diode line is not working, I dont how to run it please help, i really want to know how to initialize the diode part, everything works fine, only this part when i add it it says ISimulation model not found usingSystem;usingSpiceSharp;usingSpiceSharp.Components...
One important example is the two-diode model, originally introduced by [16]. The inclusion of the additional diode increases the parameters from five (for Rp-model) to seven. The main challenge now is to estimate the values of all the model parameters while maintaining a reasonable simulation ...
To get the clipping in the diagram you'll need to use ideal diodes in spice that have a better roll off. If you want to build a more realistic circuit, try bringing down the resistor below 400Ω (lower the better until but still limit current from the opamp) and ditch the capacitor....
