Simple Transistor Amplifier Circuit Diagram The output signal phase shift is 180⁰, hence the output and input are inverse to each other.Ĭomponents Required for a Transistor Amplifier Circuit This configuration is most used configuration among all the three, as it has average input and output impedance value. The current gain (Beta) is defined by the ratio of collector current and base current in this configuration. In this configuration, the sum of collector and base current is equal to the emitter current. Here, the input parameters are V BE and I B and output parameters are V CE and I C. This configuration is an inverting amplifier circuit. Input is supplied to the base terminal and the emitter is common for the Input and Output. In the CE (Common-Emitter) Configuration, we get output from the collector terminal. For, learning about other two configuration, types of transistors and their working follow the linked article. Here, we are explaining Common-Emitter configuration, as it is the most used and popular configuration.
