Hi,
A thought just occurred to me just a while ago. In a common emitter amplifier the transistor pretty much compresses the top of the voltage swing and stretches the bottom of the swing. However due to the inversion the polarity is reversed. If you were to feed it into another common emitter stage wouldn't it cancel it out.
I am sure there must be some other Alec who has thought of it. I just wondered what the answer of it would be.
Thanks,
Oon

If you attenuated it and fed it into another identical stage then the second-order distortion would cancel. You would still get third-order distortion from the two lots of second interacting. Negative feedback achieves a similar result, but does not require careful stage matching so people prefer it.
