Any engineers or electronics enthusiasts in the crowd?
By Tuesday, I have to design an audio frequency (AF) amplifier. They gave me the diagram...
And the specs:
Rin (input resistance): between 23 and 27 Ohms
Av (Voltage gain): between 100 and 130
Vo (output voltage): 3 Volts peak to peak (ideally sine wave from -1.5V to 1.5V)
And some crap about 3dB points, I'll figure that out later
So it's basically finding the values of the resistors in that diagram by looking at each BJT (Bipolar Junction Transistor). Now, I'm stuck on the first transistor, because it's in there all funny (all the examples in my notes and the book are given in the orientation of the right transistor).
1) Had to do a similar assignment?
2) Worked with these?
3) Acquired knowledge of transistor-based amplifiers?
The only help I really need is the method of madness to solve it. Chances are if you're still reading this, you might know what all of this stuff is! So right now I'm taking the left half of the circuit and trying to make it into its small scale equivalent to find input/output voltage, resistance, etc. Don't know why I'm doing it, but I am
Commom Base Amplifier... although I expect no one to be able to help me (due to it not being fun ), if you do, that's a helpful document.
Thanks, if anything, I provided some humor for being stuck on this!
