While the addition of the sidestep capacitor, CE aids to manage the amplifiers gain by counteracting the results of the uncertainty of beta, ( β ), one of its primary downsides is that at high regularities the capacitors reactance becomes so reduced that it effectively shorts out the emitter resistance, RE as the regularity increases.

 

The result is that at high regularities the reactance of the capacitor allows very little A/C feedback control considering that RE needs out which additionally indicates that the Air Conditioning voltage gain of the transistor is substantially raised driving the amplifier into saturation.
One easy method of controlling the amplifiers gain over the entire operating frequency array is to divide the emitter resistance right into two components as shown.
