Common-base configuration, Electrical Engineering

Common-base configuration:

 The common-base that is abbreviated as CB transistor configuration, which is as well termed as the 'grounded base' configuration, is displayed in figure.  In this configuration, the terminal common to both the input and the output of the circuit is the base.

 The output voltage and input current of the common-base configuration that are the emitter current Ie and the collector-base voltage Vcb, correspondingly, are frequently considered as the independent variables in this circuit. The dependent variables of it, on the other hand, are the emitter-base voltage Veb (that is the input voltage) and the collector current Ic (that is the output current).  A plot of the output current Ic against the collector-base voltage Vcb for different values of Ie might be drawn for easier analysis of a input or output characteristics of transistor, as displayed in this figure of Vcb-Ic Curves.
