Module 16: Model Q2N2222 used by Q_Q1 is undefined

I have been working through the "Mixed-signal Simulation with TI-PSpice 2020" workbook. I have come up against an issue I have had a difficult time resolving in the final module. Module 16 "Noise Analysis with PSpice" brings up an error "ERROR(ORPSIM-15113): Model Q2N2222 used by Q_Q1 is undefined". I have tried looking around for a resolution without any meaningful success. If anyone could recommend a resolution or where I may find a resolution to allow for me to complete this module it would be greatly appreciated.

 

Thanks

PSpiceforTI doesn't have a lot of discrete transistors in the library that comes with the software.  If you have any of the Cadence libraries that come with PSpice A/D the model is in the bipolar.lib file.  By the way, where did you pickup that Mixed-signal Simulation workbook?

Hello @retiredEE, 

 

Here are the two links I used. I don't recall how I came across them but either way, enjoy.

Module 16 uses four Q2N2222 transistors.  When I opened Example.opj with PSpiceforTI I received a warning that the model for these parts isn't in the configured libraries.  If you don't have bipolar.lib you can get a 2N2222a model from ON semiconductor and, following the Module 12 example, configure it to use in that circuit to finish Module 16.
