Did you know?
The electronic circuit which performs amplification is known as an Amplifier. The transistor is the main component in Amplifiers. Bipolar Junction Transistor (BJT) is the basic transistor among all transistors. So, if we use BJTin the amplifier circuits, those are known as BJT amplifiers. See more We can classify the BJT amplifiers in various ways based on different parameters. One of those parameters is the BJT configuration. Since we have three BJT amplifier configurations, we will get three types of … See more As the name implies, Base is common to both input and output in the Common Base (CB) configuration. Here, we will consider the Emitter and Collector terminals of the BJT … See more As the name implies, Collector is common to input and output in the Common Collector configuration. Here, we will consider the Base and Emitter terminals of the BJT as the input and output terminals. The BJT Amplifier's … See more As the name implies, an Emitter is common to both input and output in the Common Emitter (CE) configuration.
