Hello everyone
I hope you're all well...
I'm trying to amplify an electret microphone signal using an NPN transistor and have a circuit which managed to give me a gain of 100 approximately...
However I need a gain of approximately 400..... I amplified my original input signal by a common emitter configuration... the circuit is attached below...
The varying voltage source represents my microphone input...
I was obviously able to amplify my input signal of 10mV by small signal amplification... I can't further amplify by another amplifier stage right? because my output from the first stage is around 1.2V which is no longer a small signal... so how can I further amplify this to around 4V?
Furthermore, please if you have any notes regarding the circuit do tell!!
Thank you
