The common emitter circuit has an input loop and an output loop a bjt one way to use it as an amplifier or switch is to connect it in the common emitter configuration in the common emitter configuration, the input port of the bjt is the. The basic transistor amplifier circuit is indicated below: it is called a common emitter amplifier since the emitter is common to both the input circuti and the. Electronics tutorial about the common emitter amplifier and transistor amplifier circuits including its load line graph and calculations. The article is about what is a common emitter amplifier, working, voltage & current gain, characteristics, applications, advantages and its disadvantages.
In electronics, a common-emitter amplifier is one of three basic single-stage bipolar-junction-transistor (bjt) amplifier topologies, typically used as the voltage . They apparently set the rc/re ratio to 3 because they wanted a voltage gain of about 3 presumably that was desirable for the role of this circuit. This is a common-emitter amplifier, which amplifies the input voltage about 10 times the capacitor and the 110k and 10k resistors bias the transistor's base at.
