ex this amplifier which is biased by I from Q2.

makes sense now. i see biasing often done with current sources usually at the emitter of the npn. is there a way to easily choose this bias current to design for a specific transfer function with respect to changing input voltage, or does it require a small signal model and calculating the...

Can someone clarify the overall purpose and implications of biasing a BJT Class A amplifier? I just can't get my head wrapped around the entire purpose. As far as I know, biasing the circuit will place it in a certain operating region, but I don't know the limits/implications of doing this...
