What attracts a lot of people to amateur radio is that it gives you the ability to make your own gear. Scratch-building hams usually start by making their own antennas, but eventually, the itch to ...
In the early days, PNP bipolar transistors were common, but the bulk of circuits you see today use NPN transistors. As [Aaron Danner] points out, many people think PNP transistors are “backward” but ...
Scientists have created an n-channel transistor using diamond for the first time, potentially leading to faster components that can work in extreme conditions. When you purchase through links on our ...
There's been no greater act of magic in technology than the sleight of hand performed by Moore's Law. Electronic components that once fit in your palm have long gone atomic, vanishing from our world ...
If the claim is accurate, it would mean that China has bleeding-edge tech that could rival chips from Intel and TSMC. Share on Facebook (opens in a new window) Share on X (opens in a new window) Share ...
Lab-on-a-chip is a class of devices that can revolutionize the natural working of a laboratory, with multiple laboratory techniques being integrated and automated in a system that fits into a chip of ...
Figure 1 shows a variation on a sine wave oscillator, it uses just two transistors and a single variable resistor to set the frequency. Figure 1 Just a couple of components are needed for a simple ...
Fast switching: the Hybrid Photonics Labs at Skoltech where the new optical transistor was created. (Courtesy: Skoltech) A new optical transistor has been designed by researchers in Russia, ...
