Types of Transistors: BJT and FET
Transistors are classified into two categories: bipolar junction transistor (BJT) and field-effect transistor (FET). These semiconductor devices have revolutionized the world of electronics with their ability to amplify and switch electric currents.
BJT, or bipolar junction transistor, is one of the earliest types of transistors. It consists of three layers of semiconductor material and can amplify current or act as a switch. BJT transistors are commonly used in applications such as audio amplifiers and power regulators.
FET, or field-effect transistor, is another type of transistor that operates based on the electric field generated by the input signal. It has three terminals: source, gate, and drain. FET transistors offer high input impedance and low output impedance, making them suitable for applications such as integrated circuits and digital logic gates.
Comparison between BJT and FET Transistors
| BJT | FET |
|---|---|
| Requires current to flow through the base-emitter junction | Operates by controlling the flow of majority charge carriers |
| High power dissipation | Low power dissipation |
| Lower input impedance | Higher input impedance |

Origins of the Field-Effect Transistor
The concept of the field-effect transistor was first proposed by Julius Edgar Lilienfeld in 1925. Lilienfeld, an Austrian-Hungarian physicist and engineer, envisioned a device that could control the flow of current in a semiconductor material through an electric field. Although his idea was groundbreaking, Lilienfeld was unable to construct a working prototype at the time.
It wasn’t until over two decades later that Lilienfeld’s concept would become a reality. In 1947, at Bell Laboratories, John Bardeen, Walter Brattain, and William Shockley invented the first working transistors, which included both bipolar junction transistors (BJTs) and field-effect transistors (FETs). Building upon Lilienfeld’s idea, they successfully demonstrated the functioning of FETs, which utilized an electric field to control the conductivity of a semiconductor material.
The invention of the field-effect transistor opened up a new era in electronics.
