Types and function of transistor
Types and function of transistor A transistor is a type of electronic component that is used to amplify or switch electrical signals. It is an essential building block in modern electronic devices and is used in a wide range of applications, from radios and televisions to computers and mobile phones. The first transistor was invented in 1947 by John Bardeen, Walter Brattain, and William Shockley at Bell Labs. Since then, transistors have become smaller and more efficient, leading to the development of more advanced electronics. Types of Transistors: There are two main types of transistors: bipolar junction transistors (BJTs) and field-effect transistors (FETs). Both of these types of transistors have their own advantages and disadvantages, and they are used in different applications. Bipolar Junction Transistors (BJTs): BJTs are the most common type of transistor, and they are used in a wide range of applications. They are made up of three layers of semiconductor material: the
