9/12/2023 0 Comments Define transistor and its typesOne is the Emitter-base junction, and the other is Collector- base junction. Thus, there are two junctions of the transistors. Thus, as there are three terminals of the transistor, i.e. The transistor as its names suggests transfer resistance from one channel to other channels. We will discuss functions of these three terminals in the working of the transistor.Ī transistor is a semiconductor device, so the semiconductor material used in its construction can be either germanium or silicon, but silicon is preferred over germanium because it possesses smaller cutoff current. The three terminals have specific names that are as follows:. The transistor formed in the former case will be NPN transistor and that formed in the latter case is PNP transistor. We can use either sandwiched P-type layer of the semiconductor between two N-type semiconductors or by sandwiching N-type layer between two P-type semiconductor specimen. A diode is two terminal device, thus, if we merge the two diodes provided that one terminal is common, the resulting device will comprise of three terminals. Let’s discuss constructional features of the transistor, how this 3 terminal device is formed. Now, all the computing devices are available in small size which we can easily carry with us anywhere. In the year 1947, John Bardeen along with William Shockley & Brattain invented the transistor. But this all has become possible with the invention of the transistor. Obviously, to work with it is a cumbersome process.įortunately, we have compact size processing system in the contemporary world. Now you can imagine what will happen if the entire room consists of a single processing system. This is because devices such as computers were entirely based on them.īut the problem started with their size which can capture the entire room. In the beginning of 20 th century when the vacuum triode was invented, it was considered as the significant development in the field of electronics. Let me explain this with the subvention of history.
