Below is the Mini Audio Amplifier Circuit With BC547. All components with their values are available but assume that I want to calculate and design from from scratch what necessary steps should I do?
First for battery, I'll pick 3V.
The first stage is a common emitter with gain Rc/re with re = 25mV/Ic.
Second stage is also common emitter with PNP transistor.
The third stage is a push-pull to drive load.
Assume that I use this Electret Condenser Microphone how do you assign gain and bias current for each stage?
What step should I do in order to calculate value of each component and make it work?
