The common emitter circuit is probably the most widely used transistor configuration. The emitter electrode is common to both input and output circuits. The common emitter amplifier has a typical input impedance of 1kilo ohms and a typical output impedance of 10 kilo-ohms. Also, the output will be the inverse of the input, which means … Read more
BJT and MOSFET are two types of semiconductor transistors. Even though both of them are transistors, they are different from each other in various aspects. By the end of this article, you will know the difference between BJT and MOSFET. Bipolar Junction Transistors (BJT) A Bipolar junction transistor, commonly known as BJT, by its construction, … Read more
A Metal Oxide Semiconductor Field effect transistors, commonly known as MOSFET, are semiconductor switching devices that have three terminals which are the gate, drain and source. They are unipolar transistors, this means they depend on one type of charge carriers which can either be holes or electrons. They are much simpler to fabricate compared to … Read more
A Bipolar junction transistor, commonly known as BJT, is a Si or Ge semiconductor device that is structured like two p-n junction diodes connected back to back. It has two outer regions which are the emitter and collector and another region in the middle known as the base. The bipolar junction transistor is called bipolar … Read more
A transistor is an electronic semiconductor device that is used in the circuit to control, regulate and amplify electrical voltage or current signals. Nowadays, silicon is predominantly used as the material for the construction of transistors. In some cases, a combination of trivalent and pentavalent elements, like gallium−arsenide are also used. By interconnecting and embedding … Read more
Datasheets released by diode manufacturers contain a number of diode ratings. In order to select diodes for an application, it is important to understand all the ratings listed in the datasheets. Here is a list of all diode ratings that you must remember always. Diode ratings Forward voltage drop (Vf) The voltage drop measured across … Read more
PIV stands for ‘Peak Inverse Voltage’. It refers to the maximum reverse bias voltage a semiconductor diode or other semiconductor devices can withstand without damaging themselves. The peak inverse voltage is also known as peak reverse voltage. PIV rating of a diode is temperature-dependent. It increases with an increase in temperature and decreases with a … Read more
What are zener diodes? Zener diodes are silicon semiconductor devices that can allow the passage of current in both forward and reverse directions. Unlike p-n junction diodes, they are designed in such a way to handle the reverse breakdown voltage without damaging themselves. They are heavily doped than normal p-n junction diodes, thereby forming a … Read more
The bipolar junction transistors exist as NPN and PNP types. This article intents to help you understand the difference between these two types and how to use them in a circuit. Also, this will be helpful to automation engineers and instrumentation engineers in understanding 3 wire sensor connections. Transistors are made by combining two types … Read more
Introduction Circuits that are used to convert the Alternating Current (AC) input power into a Direct Current (DC) output power is known as rectifier circuits. Rectifiers are found in almost all equipment, from a low voltage battery charger to High Voltage DC transmission systems. Basically, rectifiers are classified into Controlled rectifiers and uncontrolled rectifiers. In … Read more
