Common Emitter Amplifier : Working and Its Applications
WebMay 13, 2024 · In common emitter (CE) configuration, input current or base current is denoted by I B and output current or collector current is denoted by I C. The common emitter amplifier has medium input and output impedance levels. So the current gain and voltage gain of the common emitter amplifier is medium. However, the power gain is high. WebApr 28, 2024 · To facilitate amplifier functionality with the common base configuration, we need to supply the input signal to the emitter terminal, while extracting the output from the collector terminal. Therefore, in this instance, the input current is also the emitter current. This also means that the output current is indeed the collector current. WebMeasure the AC signal voltage at the transistor’s base, emitter and collector. Measure the voltage gain of the amplifier. Observations with open C 2: 9. Replace C 2 and reduce R L to 1.0 kΩ, simulating a change in load conditions. Observe the AC signal voltage at the transistor’s base, emitter and collector.
