Bjt symbol

A Bipolar Junction Transistor (BJT) is a three-terminal device which consists of two pn-junctions formed by sandwiching either p-type or n-type semiconductor material between a pair of opposite type semiconductors. The primary function of BJT is to increase the strength of a weak signal, i.e., it acts as an amplifier.

• The bipolar junction transistor is a semiconductor device constructed with three doped regions. • These regions essentially form two ‘back-to-back’ p-n junctions in the same block of semiconductor material (silicon). • The most common use of the BJT is in linear amplifier circuits (linear means that the output is proportional to input).

May 14, 2013 · \$\begingroup\$ This is what I suspected - I don't mind a plethora of MOSFET symbols that are all takes on a similar theme but the Circuit_Lab symbol just seems to be in it's own league - it might be trying to mimic a BJT - the emitter and source (for NPN and N channel) do point the same way (now that I have become semi-accustomed to the symbol). The term bipolar refers to the use of both holes and electrons as current carriers in the transistor structure. Figure 1: Basic BJT structure. The pn junction joining the base region and the emitter region is called the base-emitter junction.

BJT is a bipolar transistor with three terminals: emitter (E), base (B) and collector (C). For the BJT symbol, emitter and collector are arranged in a line and the base is arranged vertically. There are two types of BJTs: NPN and PNP. In the BJT symbol, the emitter has an arrow and the arrow's direction tells whether it’s a PNP or NPN transistor.There are four transistor types that correspond to these basic active device models. The schematic symbols for these are shown in figure 8.2.1. The n-type current controlled device is the NPN Bipolar Junction Transistor (BJT). The p-type current controlled device is the PNP BJT.
