Well, BJTs are not easily damaged by static electricity, they are cheaper and easier to bias than MOSFETs. Depending on the biasing of these two junctions, the BJT can operate in different modes.īJT, why should you be named the better transistor? Every BJT has two P-N junctions called the Emitter-Base junction (EB) and the Collector-Base Junction (CB). The slightly doped Base Region and the Collector Region which is moderately doped. It has the Emitter Region, which is highly doped. BJT is divided into three regions based on doping. They are regions, junctions, and modes of operation. In terms of the architecture of BJT, three big terms come to play. Like any transistor, BJT can amplify a signal or switch a high power load using a very small signal. The bipolar in the name signifies the fact that both holes and e lectrons are used in this transistor for current conduction. Let’s welcome our first candidate – The BJTīipolar Junction Transistor (BJT) was invented in 1948 at Bell Telephone Laboratories. We also made a tutorial on Vacuum Tubes, you can also check that out if you want to learn more about it. You can check those about if you are interested in making cool projects with them. Previously, we have built many projects that require BJTs, Transistors, or MOSFETs to work properly. Transistors are the new employees, and well, so far so good! The burning question then is, between BJT and MOSFET, who should win the employee of the year award? They require a high operating voltage (they eat a lot!) so unfortunately for them, society rendered them inefficient employees and they got fired. And when I say vacuum tubes, the first thing that comes to the mind is a big bulky device, inside which the vacuum tubes reside. Before semiconductors (particularly transistors), the only devices available for signal amplification and switching were Vacuum Tubes. In this article, we will discuss the basics of BJTs, Transistors, and MOSFETs. If you are exploring the world of electronics, and you want to know more about the Transistors and MOSFETs for your upcoming brilliant project, you are at the right place.
