In the CE (Common-Emitter) Configuration, we get output from the collector terminal. Input is supplied to the base terminal and the emitter is common for the input and output.
This particular configuration is an inverting amplifier circuit.
Here, the input parameters are VBE and IB and output parameters are VCE and IC.
In this configuration, the sum of collector and base current is equal to the emitter current. IE = IC + IB
The current gain (Beta) is defined by the ratio of collector current and base current in this configuration. Current Gain (β) = IC / IB
This configuration is popular as it has average input and output impedance values.
The output signal phase shift is 180⁰, hence the output and input are inverse to each other.
