What is output characteristic for common emitter?
In Common Emitter (CE) configuration, the emitter is the common terminal. Hence, the input is between the base and the emitter while the output is between the collector and the emitter. Two terms that you must remember: Input characteristic – the variation of the base current (IB) with the base-emitter voltage (VBE)
What is the significance of the output characteristics of the transistors in CE configuration?
The current gain of a transistor in CE configuration is defined as the ratio of output current or collector current (IC) to the input current or base current (IB). The current gain of a transistor in CE configuration is high. Therefore, the transistor in CE configuration is used for amplifying the current.
What is the characteristic curve of a CE transistor?
In CE configuration the curve draws between collector current I C and collector-emitter voltage V CE at a constant base current I B is called output characteristic. The characteristic curve for the typical NPN transistor in CE configuration is shown in the figure below.
What is the output curve of an IC transistor?
It is the function of IC collector current and VCE collector-emitter voltage at making IB Base current constant. Output characteristics curve can be obtained by keeping the input current IB constant and varying the output voltage VCE at different value and then record those values.
What are the characteristics of a common emitter transistor?
Characteristics of common emitter transistor represent the behavior of transistor for some input and output in a graphical way. By the understanding characteristics, we can easily understand about the behavior of common emitter transistor. Here we look into the input and output characteristics of the transistor.
How to calculate the input characteristics of a common emitter configuration?
Input Characteristics Curve of Common Emitter Configuration: It is the function of base current IB and VBE (base-emitter voltages) at constant collector-emitter voltage VCE. Input characteristics curve can be obtained by keeping the output voltage VCE constant and varying the input voltage VBE and then record the value.
