I don't know if i chose the right place to post my thread, but im really struggling on this one. It's about CE amplifier. Im really sorry for asking such stupid question. But I really need help on that. I have searched on the internet about this stuff, but I hadn't any luck on finding what I needed.
I had solved many problems with CE amplifiers, but all these problems had almost everything known, but they have not any practical purpose for me. I want to learn how to design my own CE amplifier by myself.
How to solve a CE amplifier problem, with almost everything unknown? The only known things are the Vcc which would be in example VCC=6V, Vbe which is stable 0.7V, and the transistor in example 2N3904 with a β at a random value say 200 according to the datasheets. My goal now is to try to find:
1) the required resistors (except Re, which can be found with Ohm's Law),
2) the capacitors,
3) the Vin (this one i need to know in order to find the maximum voltage required to drive the amplifier without signal distortion on acoustic frequencies),
4) Ic, and Ib, (because Ie = Ic + Ib)
5) the voltages Vc, Ve, Vb and Vce, and
6) the Q point of transistor (this one i need to know because not every datasheet provide DC load lines.)
Current gains and Voltage gains would be highly appreciated, but not required.
It would be highly appreciated if you could provide only the formulas. I found many formulas on the internet, but all of them are very confusing, and does not exactly answer my question. These formulas provide everything necessary you should know, but still, there is some
For one more time, thank you.
PS At the end, i have a question on number 6). How can I know if my transistor works on operating region? How to make sure it is not working on saturation or cut-off region?
