Hi all,
I've been studying the output stage of buffamp preamplifier and I am asking me if a higher quiescent current would be better for linearity.
Pspice show me an imbalance in AC currents for each output transistor, the upper transistor drives more AC signal current that the bottom one, and this might be bettered if we raising the values of resistors in NFB loop for lower AC current through output transistors.
Might be an error in pspice too...
Thanks,
