Title: Hacking BJT model file Post by yvkrishna on Aug 11th, 2012, 4:17am Hi, I wanted to explore the effects of BJT beta(current gain =ic/ib) on VBE nature w.r.t temp etc. I planned to edit the existing model file for 'BF' (ideal forward beta) value to a large number like 100 and re-simulate. does doing this make the new bjt model valid and practical or does it have some dependency to any other model parameter? Thanks, yvkrishna |
Title: Re: Hacking BJT model file Post by Geoffrey_Coram on Aug 13th, 2012, 5:40am Maks gave a nice answer to your other (related) question: http://www.designers-guide.org/Forum/YaBB.pl?num=1344685021 So, beta is related to other model parameters (or, perhaps, other model parameters capture other aspects of the same underlying physics). That said, you can probably change beta by a factor of 2 and still have a "reasonable" model. |
