NPN Transistor Tutorial - The Bipolar NPN Transistor
In this tutorial about bipolar transistors we will look more closely at the “Common Emitter” configuration using the Bipolar NPN Transistor with an example of the construction of a NPN transistor along with the transistors current flow characteristics is given below.
Bipolar Junction Transistor (BJT) – Formulas and Equations
Formula & Equations for Bipolar Junction Transistor "BJT". Common Base, Common Emitter Common & Collector BJT Equations. Current Gain, α & β.
Here we will describe the system characteristics of the BJT configuration and explore its use in fundamental signal shaping and amplifier circuits. The BJT is a three terminal device and it comes in two different types. The npn BJT and the pnp BJT. The BJT symbols and their corresponding block diagrams are shown on Figure 1.

Bipolar junction transistor - Wikipedia
3D model of a TO-92 package, commonly used for small bipolar transistors. A bipolar junction transistor (BJT) is a type of transistor that uses both electrons and electron holes as charge carriers. In contrast, a unipolar transistor, such as a field-effect transistor (FET), uses only one kind of charge carrier.
Bipolar Transistors are current regulating devices that control the amount of current flowing through them in proportion to the amount of biasing voltage applied to their base terminal acting like a current-controlled switch.
In this section we discuss the main principles behind the operation of the BJT. The NPN bipolar transistor consists of 2 NP-PN junctions, as depicted in Fig. 5.1.a. The bipolar device is composed of two diodes back to back with different doping profiles; the BJT has 3 terminals labeled as E(Emitter), B(Base) and C(Collector).

Transistors - Practical EE
Transistors are semiconductor devices that are used to amplify or switch on and off electric signals. There are two main types of transistors: bipolar junction transistors (BJT), and field effect transistors (FET).
