So I built the following circuit to amplify the output from my microphone. I am testing it using a 1KHz sinewave of 10mV peak value. The Mic is biased using a 10k resistor. The signal is input into a common emitter amplifier with a AC gain of around 115. Next to connect the speaker, I used a Common Collector stage to increase the input impedance seen by the first stage.
However, when I connect the speaker, the output is as follows:
I know this is a problem of the low resistance load, but I would like to hear a possible solution for this problem. Do I need to add another stage?
