WebThis changing ability makes it able to perform both as an “Amplifier” or a “Switch”. It can be used either as a switch or an amplifier at a single time. Therefore, BJT can operate in three different regions to perform the said operation. Active Region: In Active region, one of the junctions is in a forward bias while the other is in reverse bias.
WebSep 30, 2024 · What is BJT Amplifier? 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 BJT in the amplifier circuits, those are known as BJT amplifiers.
