If you have any material (books, links, articles) on transistors i would appreciate that. I am looking for a way to get more general knowledge on subject. Thank you.
there are 100's of tutorials text and videos onlineIf you have any material (books, links, articles) on transistors i would appreciate that. I am looking for a way to get more general knowledge on subject. Thank you.
They are both correct? Current is dependent on a voltage, so there must always be a voltage for there to be a current.Voq - if you want to gain more and deeper knowledge on "how a transistoir works", I think the following hint is very important:
Comparing different knowledge sources (books, articles, internet contributions) you will - surprisingly - notice that two different explanations still exist:
1.) BJT as a current-controlled device: The collector current Ic is a result of (and will be controlled by) the base current Ib
2.) BJT as a voltage-controlled device: The collector current Ic is a result of (and will be controlled by) the base-emitter voltage Vbe.
Apparently, only one answer (physical working principle) can be correct. In the past, this subject was already intensively discussed - also in this forum.
An answer to this question may be of less inportance as long as you are using only formulas and design strategies readily available for building transistor amplifiers.
However, if you want to know what`s really going on and if you want to discover new application areas it is of great importance to know if answer 1) or answer 2) gives the correct description.
In this context, I recommend all BJT-related contributions from the universities of Berkeley and Stanford as well as from the MIT.
(Don`t rely on some obscure and simplified online tutorials) .
