What is Electronics?
Electronics is the branch of science
deals with the study of flow and control of electrons
study of behavior of electrons and their effects in vacuums, gases, and semiconductors
Devices (electronic components) for control of such electrons.
What sets electronic circuits different from electrical circuits is its ability to make decisions, process information, and interpret a signal or instruction to perform a task.
Development of Electronic Devices:
William Gilbert is the one coined the word electricus, while on his pioneering research on magnetism and static electricity.
Every electronics engineer had encountered Robert Kirchhoff, famous for the Kirchhoff’s Laws
With a record of 1,093 patents which comprise key and minor innovations(though early inventions was never patented), Thomas Alva Edison is perhaps the most celebrated inventor in American history
The inventor of the oscillation diode valve or vacuum tube, John Ambrose Fleming is the one who set the benchmark for modern electronics, which why he is regarded as the father of modern electronics
Lee De Forest who invented the Audion vacuum tube, which made live radio broadcasting possible before the invention of the transistor
Walter Schottky who laid work in solid-state physics and electronics, discovered an irregularity in the emission of thermions
Philo Taylor Farnsworth is the man who invented the electronic television, at only age 21.
The transistor era began with the junction transistor invention in 1948; this particular invention got a Nobel Prize.William B. Shockley worked on semiconductor to control and amplify electronic signals, with John Bardeen and Walter Brattain.
The subsequent years (1958 to 1975) witnessed the invention of the integrated circuits (ICs) that drastically changed the electronic circuits’ nature as the entire electronic circuit got integrated on a single chip JFETS and MOSFETs that were developed during 1951 to 1958 by improving the device designing process and by making more reliable and powerful transistor
Digital integrated circuits were yet another robust IC development that changed the overall architecture of computer
Later digital ICs employed PMOS, NMOS, and CMOS fabrication design technologies
