Using Qucs with a Non-linear Model of a Transistor.

Tonight I posted a new video. The video shows how to find the parameter values for a non-linear model of the transistor. This is the best possible model. However, remember it is just a model and there is significant manufacturing tolerances in transistors. The simple model we have been using allowed us to do a lot of things the most significant being we were able to test various values of Beta and make sure our circuit was tolerant of those. However, the non-linear model has a much better chance of being closer to the actual circuit once we test it.

The next video about Qucs will show what happens when you make an error inputting parameters or drawing a schematic.  Qucs does provide some messages to locate those errors but it does take some work to find the message and the errors.
