EEE 111L The Input-Output Characteristics of CE (common emitter) Configuration of BJT LABREPORT-05 North South University Department of Electrical & Computer Engineering Course Code: EEE111L Course Title: Analog Experiment name: The Input-Output characteristics of CE (common emitter) configuration of BJT. Objectives: ● Study of the input-output characteristics of CE (common emitter) configuration of BJT. Apparatus: ● Transistor (2N2222A) ●Resistor(100KΩ,1KΩ) ● Trainer Board ●DC powersupply ● Digital Multimeter ●Chordsandwire Theory: A transistor has three doped regions which are emitter, base, collector. In a transistor where the emitter is connected to both base and collector, we call it a common emitter transistor configuration. In common emitting transistors configuration input is taken from both emitter and base and the output is taken from the emitter and collector. There are three different currents in a transistor. They are emitter current, collector current and the base current. Emitter current is equal to summation of collector current and the base current. We can measure transistor characteristics from two characteristic curves which are input characteristics curve and output characteristics curve.
