I just want detail information about BJT circuits
Look at these two attachments.
The first attachment shows the quiescent dc voltages and electron currents for a simple npn circuit. The second one shows the ac signal output using a 1-volt peak input signal on the base.
Here is a quick intro
and a Hybrid-pi model amplifier design if interested
Power Amplifier and Classification of Power Amplifier
How about you show us some effort here. What exactly are you asking about? What is the context of your questions? Is this for schoolwork? What did you think of the great information links that you were given above?
i want a detailed note on bjt biasing
Well, what kind of questions do you have on transistor biasing?
See my two attachments in post #3 for a npn BJT biasing example.
