ABSTRACT
The correlation between the simulated and the practical results depends on the accuracy of the component models used. So far, components have been assumed ideal. This chapter discusses the component models available in PSpice. There are two main types of models, passive and active. To give the user insight into how “good” or “bad” the simulation is, a comparison between the predicted and the practical results is presented in selected instances. PSpice has basic models for all passive components, and the “simpler” components have only.MODEL statements. For some of the more complex components such as crystals and transformers, PSpice has a library of models and the user must select the most appropriate model from the required library. The chapter considers the modelling of resistors, capacitors, and inductors. Most PSpice semiconductor models are developed using the program Parts, which is part of the complete PSpice simulation package.
