Bipolar transistor biasing

Bipolar transistors must be properly biased to operate correctly. In circuits made with individual devices (discrete circuits), biasing networks consisting of resistors are commonly employed. Much more elaborate biasing arrangements are used in integrated circuits, for example, bandgap voltage references and current mirrors..

Introduction to Bipolar Junction Transistor (BJT)

A Bipolar Junction Transistor, or BJT, is a type of transistor in which the current flow between the collector and the emitter is controlled by the amount of current that flows through the base. It is a type of transistor that uses both electron and hole charge carriers.

Bipolar junction transistor

A bipolar junction transistor (BJT) is a type of transistor that uses both electrons and holes as charge carriers. Unipolar transistors, such as field-effect transistors, use only one kind of charge carrier. A bipolar transistor allows a small current injected at one of its terminals to control a much larger current flowing between two other
