Can anyone help me with my assignment whereby I need to ;

Design a 3 stages voltage amplifier (1st stage, FET
amplifier, 2nd & 3rd stage BJT) that is able to
amplify input signal from microphone at 0.1V, 1-
4kHz at 150X+/- 10% to output signal at the
speaker.

 

If you can post up the work you have been able to do, we probably can. You do not indicate what aspect of the assignment is causing you problems.

 

I do not know how to design the amplifier with those type of specifications
