WebFeb 10, 2024 · Bipolar Junction Transistor (BJT) was invented in 1948 at Bell Telephone Laboratories. The bipolar in the name signifies the fact that both holes and electrons are used in this transistor for current … A transistor is a semiconductor device with at least three terminals for connection to an electric circuit. In the common case, the third terminal controls the flow of current between the other two terminals. This can be used for amplification, as in the case of a radio receiver, or for rapid switching, as in the case of digital circuits. The transistor replaced the vacuum-tube triode, also called a (thermionic) valve, which was much larger in size and used significantly more power to …
