# NPN Transistor 2N2222 fixed bias MULTISIM

I have been working on my school projects and I wanted to ask you if there is any way of editing BETA for transistor. When I click on transistor, Edit Model is not working. Anyone help me, please.. I have been trying to figure this out for hours..

• you'll have to come up with your own (modified) model. Feb 18, 2019 at 19:32
• and how to make my own modified model? Well, it would suffice just to know what the BETA itself is. I can't find it there. Feb 18, 2019 at 19:35
• You'll find that not all transistor models give you the $\beta$ directly; you'll have to understand the model you want to modify! Feb 18, 2019 at 19:37
• is there an 2n2222.cir file? with parameters inside? Does Multisim include the non-linear hFE Vce(sat) vs Ic/Ib and Rce value? Feb 18, 2019 at 20:19
