Maybe call it 2N2222-100 if you intend to give it a current gain of 100. Then modify the parameter BF= 200 to BF= 100 or whatever.

WebMar 14, 2012 · What I did is, I browsed through MOSIS site, got IBM 0.35 micron BJT NPN model whose forward beta is 100. My specification is beta = 20. So i changed that forward beta and used those parameters in spectre for simulation. This BJT model is for Bandgap reference design. Some say, dont dwelve a lot into all of the BJT model parameters. WebDCAP= statement in a BJT model by including DCAP= in the BJT’s .MODEL statement. Convergence Adding a base, collector, and emitter resistance to the BJT model improves its convergence.

I want to add BDX53C and BDX54C to LTSpice. I saw some tutorials and tried to add transistors by typing their info to standard.bjt file but I think they do not work properly, when I run the DC op pnt analysis their beta values seem to be around 100 but they are supposed to be 750.
