Brief explanation for two stage amplifier I want a DC & AC analysis. (use 2N3904 and 2N3906)

Expert Solution

The two satge amplifier is shown as:

Theory Involved :

A transistor circuit containing two stages of amplification is known as TWO STAGE AMPLIFIER. Successful application of feedback around an amplifier having large amounts of open-loop gain is done most readily if the amplifier has a simple frequency response and input and output impedance levels which minimize the interactions with the source and load. For many applications, a high input impedance and a low output impedance work well.

Benefits :

It has excellent frequency response. The gain is constant over the audio frequency range which is the reason of most importance for speech, music etc.It has lower cost since it employee’s registers and capacitors which are cheap.The circuit is very compact as the modern resisters and capacitors are small and extreamely light.

Limitations:

They tend to become noisy with age , particularly in moist climates.Impedance matching is poor.
