A line joining the emitter and the collector serves as ...Inverter (logic gate) Traditional NOT gate (inverter) symbol. In digital logic, an inverter or NOT gate is a logic gate which implements logical negation. It outputs a bit opposite of the bit that is put into it. The bits are typically implemented as two differing voltage levels.

• 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).A PNP transistor is a type of bipolar junction transistor (BJT) that consists of two p-type semiconductor layers separated by a thin n-type layer. The p-type layers are called the collector and emitter, and the n-type layer is called the base. Bipolar Junction Transistor SymbolBJT Symbols BJT Transistor Symbols. The collector and emitter form the main conductive path, and the base controls that path. To explain how a BJT works, I am going to start with an NPN.

The conduction level in a bipolar junction transistor (BJT) depends on two charge carriers – electrons and holes. The JFET, however, is a unipolar device because its conduction depends uniquely on one type of carrier – electrons (n-channel) or holes (p-channel). Other essential characteristics of the JFET are: Ease of manufacture.
