BIPOLAR DEVICE Meaning and
Definition
-
A bipolar device is a type of electronic device, commonly used in electronics and semiconductors, which operates based on the principles of bipolar junction transistors (BJTs). A BJT is a three-layered semiconductor device, consisting of two layers of either p-type or n-type material, sandwiched between a central layer of the opposite type.
A bipolar device utilizes the properties of both types of charge carriers - electrons and holes - to control the flow of current. It typically comprises two pn-junctions: an emitter-base junction and a base-collector junction. The emitter supplies majority carriers (electrons or holes) into the base, while the collector collects these majority carriers. Moreover, the base controls the current flow between the emitter and collector.
The term "bipolar" refers to the involvement of both types of carriers in the operation of this device, unlike unipolar devices that rely on either electrons (n-type) or holes (p-type) alone. Bipolar devices offer advantages such as high current gain, high frequency response, and good linearity, making them essential components in various electronic systems, including amplifiers, oscillators, and digital logic circuits.
Some common examples of bipolar devices include bipolar junction transistors (NPN or PNP), Darlington transistors, and multilayer mosfets. Due to their extensive utilization across different industrial and consumer applications, bipolar devices play a crucial role in modern electronics and are vital components in the advancement of technology.

Etymology of BIPOLAR DEVICE
The word "bipolar device" does not have a unique etymology of its own. However, it can be traced back to the individual etymologies of its constituent words: "bipolar" and "device".
1. Bipolar: The term "bipolar" combines the prefix "bi-" meaning "two" and the word "polar" derived from the Greek word "polos" meaning "axis" or "end". "Polar" in the context of electricity refers to a positive or negative charge. The term "bipolar" is often used in scientific and medical contexts to describe a condition or device that has two opposing poles or extremities.
2. Device: The word "device" comes from the Latin word "divisus", meaning "divided" or "separated". It originally referred to something that was divided or separated from something else for a specific purpose.
