Branches of Electronics

Definition of Electronics 


Electronics is a science that deals with electrical devices and circuits, that operate by controlling the flow of electrons or other electrically charged particles. This branch of science deals with how electrons behave in gases, vacuum or semiconductors.
Following are the different branches of Electronics with some details about each branch -


Branches of Electronics

1.Analog electronics

Analogue electronics deals with analogue signals. Analogue signals are continuously variable signals. This is in contrast to the digital signals that generally take only two levels. 


2.Digital electronics

The digital electronics deals with digital signals. Digital Signals are the signals that take usually 2 levels.


3.Power electronics

Power Electronics acts as an interface between the electrical source and electrical load. It is the application of solid state electronics to the control and conversion of electric power.


4.Microelectronics 

As clear by the name itself, microelectronics is the branch of Electronics that is related to the electronic designs at very small level.


5.Circuit design

The circuit design includes, designing basic electronic components to complex electronic systems.


6.Integrated circuits

Integrated circuits are commonly known as IC in short. An integrated circuit is a small chip that may contain millions of electronic components like resistors, capacitors or transistors. 


7.Optoelectronics

As the name suggests, the optoelectronics is the branch of Electronics that combines optics (light) with electronics. It includes the use of light sources, light detectors and mechanism to carry and control light.


8.Embedded systems 

Embedded systems are the systems that are designed to perform a fixed function with no or minimum human interference. Embedded systems are controlled by a real time operating system and are the combination of computer hardware and software.


9.Semiconductor devices

Semiconductor devices make use of semiconductor materials like silicon, Germanium, gallium arsenide. The conductivity of semiconductors lie between that of conductors and insulators.

Active and Passive Components

Different types of passive electrical components and active electrical components are used in electronics.
A passive component is a component that does not produce any energy but consumes energy or is not capable of power gain. Most commonly used passive components in electronics are resistors, capacitors and inductors. If an electronic circuit is completely made up of passive electrical components then it is known as a passive circuit.
While active electrical components are the components that are not passive. Common examples of active electrical components are diodes, transistors, silicon controlled rectifiers (SCR) etc.
