Flexible Transistors Ready for Mass Production

Literal flexibility may bring the power of a new transistor developed at UW-Madison to digital devices that bend and move. (Image courtesy of Jung-Hun Seo, University at Buffalo, State University of New York.) A team of engineers has created a functional flexible transistor and with it, a fast, simple...

Silicon Transistors

 Silicon transistorsDuring the 1950s, meanwhile, scientists and engineers at Bell Labs and Texas Instruments were developing advanced technologies needed to produce silicon transistors. Because of its higher melting temperature and greater reactivity, silicon was much more difficult to work with than germanium, but it offered major prospects for...

Vaccum tubes: Luckily, They’re Still Around...

In any modern day electrical device—from alarm clocks to phones to computers to televisions—you’ll find a device called a transistor. In fact, you’ll find billions of them. Transistors are the atoms of modern-day computing, combining to create the logic gates that enable computation. The invention of the transistor...

5G : It's All About the Antennas

For 5G technology to function as expected in apps from factory automation to self-driving vehicles, multiple antennas must be properly implemented.This article appeared in Microwaves & RF and has been published.When studying 5G NR operation, it’s not immediately obvious that 5G meets all of the objectives of the 3GPP standard...

Faraday's law of Induction and Lenz Law

Faraday’s experiments shows that The emf induced by a change in magnetic flux depends on only a few factors. First, emf is directly proportional to the change in flux ΔΦ. Secondly, emf is greatest when the change in time Δt is smallest—that is, emf is inversely proportional to Δt....

Introduction to Electrical Machines

What is an Electrical Machines ? An electrical machine is a device which converts mechanical energy into electrical energy or vice versa. Electric Machines also include transformers, which do conversion between "mechanical and electrical form but they convert AC current from one voltage level to another voltage level".          ...

Introduction to Amplifiers

Amplifier is used to increase the amplitude of a signal waveform, without changing other parameters of the waveform such as frequency or wave shape. They are one of the most commonly used circuits in electronics and perform a variety of functions in a great many electronic systems. In "Electronics”...
