Science Buddies: "Ask an Expert"

Design an audio amplifier ( class AB output stage) ICs are not allowed.
load resistance is 10 ohm.Max.gain in mid band should be greater or equal to 300.
output swing should be 10 volt peak. input impedance should be 10K ohm.lower frequency should be less than or equal to 10 hertz. higher frequency should be greater or equal to 30KHz.
DC output voltage less than or equal to 100mV. quiescent current less than or equal to 10mA.

Take a look at the following web site: http://www.circuitstoday.com/few-transi ... r-circuits. This circuit uses no ICs. I would suggest varying the component values to meet the parameters that you listed. Good Luck.

give me an idea to use darlington pair based class ab output stage
