The Varactor diodes belong to the family of semiconductor devices. These are special purpose diodes, also called a varicap diodes or tuning diodes or variable capacitance diodes, designed to work …

## Difference Between JFET and MOSFET

Although in the previous lectures we discussed briefly the working of JFET (Junction Field Effect Transistor) and MOSFET (Metal Oxide Semiconductor Field Effect Transistor). But many times my students …

## How does Silicon Controlled Rectifier work? (Internal structure, Characteristic Curves)

SCR (Silicon controlled rectifier or semiconductor controlled rectifier) is an electric device which comprises four pnpn layers with three major terminals anode, cathode and gate. The device has usage …

## Understand Hexadecimal Number| Uses and Conversion Methods

What is a hexadecimal number system? Unlike decimal and binary numbers which use base 10 and 2 respectively. Hexadecimal base or radix is 16. Hexadecimal refers to number 16. Hexadecimal numbering …

## What are Binary Numbers?

Our decimal number system uses base or radix “10”. Because we use 10 digits to represent a number. But the binary number system uses base “2” because it uses only two digits zero (0) and one (1) to …

## MOSFET Basics | Working, Types, Characteristics and Applications

Working principle of an Field Effect Transistor FET is a transistor in which current is controlled by varying the resistance of the channel from where the current is passing. The resistance is …
