Op Amps: Models & Accuracy

A circuit simulation is only as good as the models used in the simulation. The more accurate the model, the more accurate the result. Unfortunately, as a general rule, the more accurate the model, the more complex it is, and the greater the computation time for the simulation. We examine a few issues regarding models in general, and op amps specifically, in this video.

The variations between simulations and reality bothered me until I realised that there are so many variables. Simulations are great for calculating values in the first instance.
Thanks for your time and knowledge. It's not about better, it's about appropriate.

"Appropriate" definitely is a watchword here.
