1. 
   Common emitter
   == Characteristics == At low frequencies and using a simplified hybrid-pi model, the following small-signal characteristics can be derived. The Miller effect negatively affects the performance of the common-source amplifier in the same way (and has similar solutions).When an AC signal is applied to...
