BJT Amplifier - Circuit, Types & Details [GATE Notes]

WebDec 7, 2024 · For example, whenever I see a CE amplifier circuit I also see a CC circuit immediately, as well, since the emitter follows the base and seeing it as CC can help me see better how the CE perspective works. If I add some NFB back to the emitter node, then I now have also added CB to the picture. And it's still the same BJT in the same exact circuit! In electronics, a common-emitter amplifier is one of three basic single-stage bipolar-junction-transistor (BJT) amplifier topologies, typically used as a voltage amplifier. It offers high current gain (typically 200), medium input resistance and a high output resistance. The output of a common emitter amplifier is 180 degrees out of phase to the input signal. In this circuit, the base terminal of the transistor serves as the input, the collector is the output, a…
