Should i consider using a CC for the OUTPUT or a class B power amplifier?

oo, thanks for the info guys

i see... (*digesting it)

Let a simple concept of an audio amplifier is to be designed like this (in BJT) : CC *CE* CE * OUTPUT ... and CC acts as a buffer. Why does a buffer is required for the amplification? Wouldn't it be much more simpler if CC is being canceled out? CC = Common Collector CE= Common Emitter...

1. As compared to the circuit as shown in the figure, i applied KCL in the circuit and still couldn't get the right Ic current at the collector as shown in the simulation. 2. The IC current for XMM2 is 1.64mA but i got 22.12mA instead in my calculation. (I'm using the Ic=βIb where...
