I have a question that has been confusing me lately and I'd sure be grateful for an answer to it. I've been playing with voltage amplifiers, especially common emitter circuits, and, just like the book says, if I try to amplify a signal larger than about 10 mV, the amplifier distorts the output.
Here is my question. Starting with 1 microvolt at the antenae of a receiver, how do I turn that into, say, +/- 20 volts into an 8 ohm load? I can amplify up to 10mV, no problem, and then with a gain of 1000(!) I can turn that into 10 volts. But that amplifier must be a single stage and has all kinds of problems with stability and noise.
What's the solution?
