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...
