What is the purpose of the emitter bypass capacitor in the Common ...
The Common Emitter (CE) amplifier''s emitter resistor is one of several key components used to set the gain of the amplifier stage. It performs this operation by limiting the amount of negative feedback applied to the amplifier stage. The short answer is that the emitter bypass capacitor increases the amplifier''s gain by suppressing the feedback. …
