Hello, I want to design a common emitter 2 stage amplifier with the 2n3904 and 12v vcc but I have not found a good reference to calculate the values for the following circuit.

try https://leap.tardate.com/electronics101/bjt/twostagecommonemitteramplifier/Hello, I want to design a common emitter 2 stage amplifier with the 2n3904 and 12v vcc but I have not found a good reference to calculate the values for the following circuit.
It is a project, they told me that I choose the values but I did not understand very well what he was referring to, what I have searched for on the internet does not have what I am looking for for this designAnd... what's your question? What are the specs you are trying to meet? What gain? What frequency range? What input impedance, What input voltage range? What output voltage range? What output impedance?
Is this some sort of homework project/assignment?
((VCC-0.7-(0.5*VCC/RC1)*RE1)/RB2)*B@(0.5*VCC) = (0.5*VCC)/(RC1+RE1)If my circuit does not require these resistors, how are the equations modified?
What do you mean by scrolled up?and i have a question why the output of stage 1 scrolled up?
Hi,Well, I was guided by this pdf https://learnabout-electronics.org/Downloads/amplifiers-module-02.pdf beta 100 and I simulated it with an input of 0.1Vp 1kHz with the 2n2222 and it worked
and i have a question why the output of stage 1 scrolled up?
