What is stabillity factor for emitter biased transistor?

Question

I need derivation of the formulae. And also if you can provide me a good site for electronics study. Thanks in advance

Answer 1

This site may be helpful, as well as provide additional links. For more detailed info. try Analog Devices, National Semiconductor web sites. They have a wealth of engineering information. Not sure of your application being rf or logic, rf being the most critical for s-factor. Good luck and hope this helps.
