These transistors are equivalent to two MOSFET transistors connected in series.

#Transistor meaning series

In a Dual Gate MOSFET transistor, two gates are present instead of one in series along the length of the channel. These types of transistors are used as resistors, amplifiers, switches, etc. The JFET transistor is a type of transistor in which there is no p-junction but a narrow region of high resistivity semiconductor allows the majority of charge carriers to flow between the source and the drain. They are used mostly for amplifying weak signals. FETs use very little current due to their high impedance. In these transistors, the voltage at the gate controls the current flow from the source to the drain. They have three terminals which are named as gate, source and drain.

They provide faster switching speeds.įield Effect Transistors (FET) are voltage-controlled semiconductor devices. In other words, it is a switching device which regulates and amplify the electrical signal likes voltage or current. The words trans mean transfer property and istor mean resistance property offered to the junctions. Such transistors are used in digital or analog microwave applications with high frequency. Definition: The transistor is a semiconductor device which transfers a weak signal from low resistance circuit to high resistance circuit. Heterojunction bipolar transistor (HBT) is a type of BJT in which the emitter and the base regions of the transistor are made from different semiconductor materials. Such transistors can be made either by connecting two transistors or are available as an integrated circuit chip. In such transistors, two discrete transistors are joined together. The Darlington Transistor was invented by Sidney Darlington. The use of the diode prevents the transistor from saturating by diverting the extreme input currents. Schottky TransistorĪ Schottky transistor is a junction transistor joined with a Schottky diode. It is used to switch between high currents in less than nanoseconds. Operations of the transistor in the avalanche breakdown region are called avalanche mode operations. Avalanche TransistorĪvalanche Transistors are junction transistors in which the collector-current/collector-to-emitter voltage characteristics are beyond the collector-to-emitter breakdown voltage. It was developed by Bell laboratories in 1954. The Diffusion Transistor is a type of transistor where the N-type silicon part called the substrate, has P-type or N-type gaseous impurities as dopants. If a low amount of current flows through the base, then a large amount of current would flow through the emitter to the collector.īJTs can be used in circuits as an amplifier, filter, rectifier, etc. BJTs are current-controlled semiconductor devices. The Bipolar Junction transistors are a type of transistors in which a PN junction exists and both the holes and electrons are required for conducting current. 1 : a solid-state electronic device that is used to control the flow of electricity in electronic equipment and usually consists of a small block of a semiconductor (such as germanium) with at least three electrodes. Transistors are classified according to their structure and their uses: Bipolar Junction Transistor
