Common Emitter Transistor Circuit Diagram. The characteristic of the common emitter transistor circuit is shown in the figure below. Here emitter is the terminal common to the input side and the output side and this terminal has been grounded.
Common emitter amplifier circuit diagram in most of the electronic circuits we use commonly npn transistor configuration which is known as npn transistor amplifier circuit. Figure 1 gives the basic circuit of ce amplifier using npn transistor bias through use of resistor r b here capacitor c b1 acts as the coupling capacitor to couple the input signal to the base to emitter terminals of the transistor one end of the input voltage v i is at the ground potential. The supply voltage between base and emitter is denoted by v be while the supply voltage between collector and emitter is denoted by v ce.

Circuit description of common emitter ce amplifier. The base to emitter voltage varies by adjusting the potentiometer r 1. The ce configuration is the one most widely used in transistor circuits. As an audio amplifier as a basic switch for logic circuits as a general analogue amplifier and in many.
