I observe the characteristics of the BC548 transistor in the transistor comparison table published by the ECA
The characteristics in your calculations do not match. If you are kind enough to tell me which book you are referring to. I thank
The above calculator is a standard transistor calculator software, so it cannot be wrong, but I have no idea why and how it may not be matching with your specified comparison table.
Glad to see somebody did this. I think it could be expanded to provide most or all of the numbers required for Dual Feedback Transistor Biasing if the right numbers are fed into it. Most of the numbers on https://www.electronics-tutorials.ws/amplifier/transistor-biasing.html for example could be worked out. I think, right now I want to build a preamp, not write a program.

JOHN CROW says
Can you tell me the formula for this calculation?
Swagatam says
R = (base input Voltage – 0.6) / Collector load current

Thank You

What means NAN
Swagatam says
not a number

Pls I want to begin with wireless circuits
Hamid Hussain says
Vce if bc548 is very low
Hamid Hussain says
If the transistor is bc547 what should be base resistor
Swagatam says
Vce is the saturation voltage (minimum).
for BC547 you have to only consider the hFe and the RL, rest all can be as it is
