How to Design portable audio amplifier, powered by a 12-V battery using the following:
-2N3904 Common Emitter Amplifier (voltage amplifier)
-2N2222A Emitter Follower (current amplifier, speaker driver)

Record the following specifications
-DC current gain hFE
-Maximum collector current
-Maximum power dissipation
-Transition frequency fT

Please refer to the design specifications:
-Power supply = 12-V
-Microphone pre-amp : Vs = 2 mV peak ; Rs = 600 ohms
-Load (speaker): RL = 8 ohms ; VL <= 0.8V peak
-Frequency Range : 300Hz < f < 3.4 kHz

*Using Multisim live or any electrical/electronics circuit with Oscilloscope to running the circuit simulator with input from frequency generator and output in oscilloscope, showing the given frequency range and without distortion on the output. Can you also give me a draft of circuit of that. Thanks

 

You need to provide your best effort to work your assignment as far as possible. We are not here to do your homework for you.

 

Hello - and welcome to the forum.
We are willing to answer your specific technical questions.
As a first step you should show as a circuit diagram which could - as to your knowledge - fulfill the requirements for gain and bandwidth.

 

If you have already designed something with or without the use of LLMs, you can share that here for a review.
