A JFET or Junction Field Effect Transistor is a transistor that classified under the category of FET. These are known for its voltage-controlled transistors where it doesn’t depend on the current for biasing. These consist of source, gate and drain as its terminals. This transistor comes under unipolar devices. The reason for this is that the conduction is dependent on the majority of the charge carriers. These FETs has the capability of consuming lesser amounts of power. It can be manufactured i … [Read more...]
What is P-Channel MOSFET : Working and Its Characteristics
P-Channel MOSFET is a classification of Metal Oxide Semiconductor Device. This consists of the n-substrate in the middle with light doping concentration. These are the three terminals devices. It possesses uni-polar characteristics because its operation is dependent on the majority of the charge carriers. In this, the majority of the carriers are holes because of two p materials utilized in the circuitry. It is further classified based on the existence of the channels. If the channel exists by … [Read more...]
Basics of N-Channel MOSFET, Working and Characteristics
N-Channel MOSFET is a type of metal oxide semiconductor field-effect transistor that is categorized under the field-effect transistors (FET). MOSFET transistor operation is based on the capacitor. This type of transistor is also known as an insulated-gate field-effect transistor (IGFET). Sometimes it is also known as a metal-insulator field-effect transistor (MIFET). This type of transistor is further classified as p-type and n-type. These p-types and n-type MOSFET’s are further classified as en … [Read more...]
Basics of FET, Working Types and Its Applications
FET stands for the Field-effect transistor. These transistors are designed to overcome the drawbacks of the bipolar junction transistors. As the basic transistors have the junction of the emitter in the mode of forwarding bias this makes the device to operate at low impedance levels. This introduces considerable amounts of noise levels. FETs possess all the characteristics which can overcome the drawbacks of bipolar junction transistors and can be a good replacement for the vacuum tubes as well … [Read more...]
What is Amplifier : Circuit Working and Its Applications
An amplifier is a basic circuit that is obtained from the transistors. These devices are designed in such a way that the transistors with the low value of the input signal are converted in terms of the signals which possess high strength. These are most widely used in the concept of long-distance communication and also at the place where the wireless data transmission is used as the media. These are the basic devices installed in the transmitters and the receivers. As the transistor is common … [Read more...]

These junctions and altogether the terminals are responsible for the generation of the current either the current controlled or the respective voltage-controlled devices are designed. This article discusses below about Transistor as a Switch along with its working and applications. The … [Read more...]
Basics of PNP Transistor – Construction, Working & Circuit Diagram
PNP Transistor is a type of bipolar junction transistor. This transistor also consists of three terminals known as collector, emitter, and base. While discussing its structure in comparison with N-P-N it is completely different. Instead of two n-types here it is two p-type semiconductors are involved in the process, whereas the separation region between these types is due to the n-type. The majority participation of the carriers in this type of transistor is due to the holes because two … [Read more...]
What is Darlington Transistor : Working and Its Applications
Darlington transistor is a pair of transistors that are connected in such a way that it enhances the features of the respective application. This transistor pair is invented by Sydney Darlington. It is formed in such a way that either two P-N-P or N-P-N transistors are connected so that the emitter of the one transistor is connected to the base of the other transistor. Both the transistors interlinked so that one can act as input other can refer to as output one. The output of the transistor … [Read more...]
What is a Bipolar Junction Transistor : Working Principle and Its Applications
The invention of the Bipolar Junction Transistor (BJT) is done in the year 1948. Transistors are the basic electronic devices that are formed because of the combination of the diodes that are referred to as bipolar junction transistor. These bought the revolutions in the modern electronic system. These inventions of transistors are the major reasons for the replacement of vacuum tubes. Individual diodes of the junction p-n that are connected back to back lead to the formation of the … [Read more...]
Uni Junction Transistor Working, Types and Applications
A Uni Junction Transistor (UJT) is a device that is formed with a single junction of p-type and the n-type of the semiconductor material. It resembles to that of the diode with a single junction of the P-N. It looks almost like that of the Junction Field Effect Transistor (JFET). But the operation is completely different in comparison with it. As the name suggesting it is a single junction transistor but it is widely used in the circuits of timing, triggering circuits and so on… it is a d … [Read more...]
