MOSFET Transistor: Basics, Operation and Types

mosfet image

Mosfet is voltage controlled field effect transistor has a metal oxide gate electrode which is electrically insulated from the main semiconductor n-channel or p-channel by a very thin layer of insulating material i.e. silicon dioxide known as glass. In our previous articles, we explain in detail about Fet operation and JFET Transistor operation. In this article, we are going to explain Mosfet types, operation, structure etc. Mosfet basics: MOSFETs generally work by electronically varying the width of a channel through which charge carriers i.e. electrons or holes travels because the device conduction is directly proportional to the channel width. The wider Read More …

JFET Transistor: Operation and Characteristics

Junction Field Effect Transistor image

JFET is the first form of field effect transistor to be developed can be used as a voltage controlled resistance or as an electronically controlled switch. In our previous articles, we explain in detail about Field Effect Transistor operation and comparison between Jfet & Mosfet. In this, we are going to explain you in detail about Jfet operation and biasing. Junction Field Effect Transistor: JFET consist of the channel of semiconducting material through which a current flows. Jfet’s are of two types; one is n-channel JFET and another is p-channel JFET. Generally, n-channel JFET are more preferred than p-channel JFET because Read More …

Field Effect Transistor: Operation and Types

FET

The field effect transistor is a three terminal unipolar semiconductor device used for weak signal amplification. This type of transistor basically uses an electric field to control the shape and hence the electrical conductivity of a channel of one type of charge carrier in a semiconductor material. FET has various similar characteristics to those of their bipolar transistor counterparts i.e. robust, cheap, high efficiency and instant operation and can be used in various electronic circuit applications. In our previous article, we explain the difference between BJT and FET, Semiconductors electronics Theory. Here we are going to explain FET operation and its Read More …

Difference between BJT and FET

FET Vs BJT image

BJT and FET both are made up of different semiconductor materials mainly P type and N type. These transistors are basically used for the designing of oscillators, amplifiers, and switches. In our last articles, we explain in detail how to use a transistor as a switch, amplifier and as an oscillator. Here we are going to explain in detail about FET and BJT basics, working and its difference. Bipolar Junction transistor: Bipolar transistor is a three terminal device formed by joining two individual signal diodes back to back, which will give us two PN junctions connected together in series that Read More …
