I've been reading up on differential amplifiers and have a question
when running the diff amp in single ended mode i see the gain is calculated by RC / 2re'.
I thought having the gain mostly dependant on the dynamic emitter resistance (re') would lead to gross distortion on the output.
However with supply rails of +/-9v and an input signal of 1mv the output is quite clean.
From experience running even 1mv into a common emitter stage with bypassed RE leads to gross non linearities in the output waveform.
Why doesnt this hold true in the differential amp?
thanks for the help guys
