Hi,
Is there a way of controlling / limiting gain when bypassing the emitter capacitor using a common emitter configuration. Putting a pot in series with the cap would form a Rc filter which i wouldn't want.
This circuit is adjusted so the Vcq is around 4.5 v (1/2 supply voltage) with 1ma through Ic & Ie. Without the bypass cap id only get a 4.5 gain factor, but if i place a volume / gain on the end to control the gain when using the Bypass to control the output it will clip hard to the point where the signal will distort when i'm after a clean boost.
Are their any trick I can use so that I can obtain a higher gain factor (say 10), have the circuit so it doesn't clip and also keep a somewhat suitable Q point for Class A?
Thanks!
