hfe parameter of bjt transistor
In any bjt datasheet, we see hfe parameter is a variant parameter because it depends on temparature. Of course, in an analog circuit we would like it mostly invariant. How can we do it?
I really need an answer about it. I think the only thing I don't understand still now on BJT is the question about hfe parameter.
Please help me. Thanks in advance.![Big grin :D :D](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
