Common-emitter configuration:
The common-emitter that is abbreviated as CE transistor configuration is displayed in figure. The transistor terminal common to both the input and the output of the circuit is the emitter in this type of configuration. The common-emitter configuration that is also termed as the 'grounded-emitter' configuration is the most extensively used among the three configurations.
Configurations
Figure: Common-Emitter Transistor Configuration
The output voltage and input current of the common-emitter configuration that are the base current Ib and the collector-emitter voltage Vce, correspondingly, are frequently considered as the independent variables in this circuit. The dependent variables of it, on the other hand, are the base-emitter voltage Vbe (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-emitter voltage Vce for dissimilar values of Ib might be drawn for easier analysis of a input or output characteristics of transistor, as displayed in this figure of Vce-Ic Curves.
Consider the point-to-point radio link introduced in problem 9. By how much must transmit power be increased to maintain the maximum BER of 10-5 if the channel is flat Rayleigh-fad
Methods of Testing Irrespective of reasons, testing is commonly carried out 1. On site, or 2. In a Meter Testing Station (MTS) accredited as per IS/ISO/IEC 17025.
