So, this should be a simple question, but I've looked through textbooks and online and while everyone says how to SOLVE a CE amp, I'm having a hard time finding anything on designing for voltage gain. Voltage gain is Vout over Vin I thought? I seem to have a negative gain on my CE stage here (Q4) and just need a gain of maybe ten (total gain of 1000-1500 for amplifier). I've been playing with the R values so don't take them as gospel, ideally for maximum swing Ill use the level shifter Q3 to bring the voltage at the base of Q4 close to 0. I can also connect it to the current mirror and steer it, but I'm not sure how much current is needed. I seem to get better performance from not including it in the current mirror.
tl;dr how do I get gain out of the CE stage? Any way I can do this without using any PNPs (I have NPNs on hand)? Thanks in advance.
