On the circuits that I am creating, the second stage, which is a Common Collector, I a gain of about 6. How or what resistors determine the gain. I am also face with the problem of the bottom swing having more gain the the top swing and in some cases saturating. What do I do? I was thinking on adding a third stage but with a gain of 5 for a total gain of 30 (5x6). I already look at some formulas relating to gain but for some reason I am not getting any good results when i aply them.
