Falstad Circuit Simulator - Transistor Graph

Recently, and after almost 15 years without touching a component, I decided to go back to my roots - electrical engineering - and annoy again transistors and other diodes. To quickly test, I use a java applet on the Falstad website.

The components are idealized, and for instance, there is only one NPN transistor - forget about the BC547 A through C, the 2N2222 and other BD135 - whose only changeable parameter is its DC gain β, 100 by default.


A need I had was to have the graph U_CE/I_c for various I_b.  I decided to plot it myself.
