I'm looking for free sources of information on designing phase-shift oscillators with custom BJT amplifiers. More specifically, I'd like to read about:
- how to calculate the phase-shift network's losses, including impedance mismatches.
- what gain do I need
- the possibility of having a high input impedance, low output impedance amplifying loop (i.e.: having the loop drive a speaker directly), but without readily-available op-amps involved
- how do I limit the output peak voltage and current
- proofs of those relationships
Shortly, I'd like to design an oscillator loop that can directly drive a speaker and have a predictable power and voltage output.
As a last resort, you could tell me about easily-obtainable but non-free sources of information if there's nothing else available that you know of.
Thanks in advance.
