What physically is the BETA of a transistor?
Date:2021/10/18 21:55:58 Hits:
Hi All, The question I ask is pretty elementary.Come to think of it, i am not even an academic and the industry I work in is different. The BETA of a transistor. What is it in physical terms. How do the manufacturers of the transistor decide how to put that beta into it,physically.Does it depend on the comparitive levels of doping or on the thickness of the base material. Now, this is where all the amplification comes from. Is it a ratio of the doping levels between the base and the collector or is it something much more complex. Ultimately, how is it that the collector current is always a multiple of the base current.Where is this ratio coming from?
I do understand the question is quite basic.And do excuse me if this question is out of context in here.
Thanks in advance
