Hi Everyone,
I have a very low amplitude ac signal (~ 2mV p-p) which I would like to amplifier using BJT's (either 2N3904 or BC548C) to achieve an output of over 1V p-p.
I am currently using a Darlington configuration with a 2N7000 and a 2N3904. Vcc is 20V but the output is not exceeding 140mV p-p.
Circuit diagram is attached.
Suggestions are appreciated.
