DRIVING DOWN THE ON RESISTANCE OF SILICON CARBIDE TRANSISTORS

DRIVING DOWN THE ON RESISTANCE OF SILICON CARBIDE TRANSISTORS

Electronics News Updates / By

UnitedSiC has developed silicon carbide transistors in standard packages with the world’s lowest on resistance. Chris Dries, CEO, talks to Nick Flaherty about the significance of the move. UnitedSiC has launched four silicon carbide SiC transistors with the world’s lowest on resistance RDS(on) to open up new applications. What we are doing is pretty incredible […]

Inside the 74181 ALU chip: die photos and reverse engineering

Electronics News Updates / By

What’s inside a TTL chip? To find out, I opened up a 74181 ALU chip, took high-resolution die photos, and reverse-engineered the chip.1 Inside I found several types of gates, implemented with interesting circuitry and unusual transistors. The 74181 was a popular chip in the 1970s used to perform calculations in the arithmetic-logic unit (ALU)

Ultralow Power Transistors Function for Years Without Batteries

Ultralow Power Transistors Function for Years Without Batteries

Electronics News Updates / By

Researchers at Cambridge University have just achieved a spectacular breakthrough in electronics design. They have developed new ultralow power transistors that could function for months or even years without a battery. These transistors look for energy from the environment around, thus reducing the amount of power used. Dr Sungsik Lee, one of the researchers at

This project uses an Arduino, a pair of speakers, and a laser pointer to create a laser projector able to trace out designs in a dark room. To power it, I’ve cannibalized a PC ATX power supply capable of delivering plenty of current for the speakers. Most of this project was directly adapted from the

Researches Solve Problems of Organic Thin Film Transistors By Developing Nanostructured Gate Dielectric

Electronics News Updates / By

Amorphous silicon-based Thin-film transistors (TFTs) are the foundation of many modern-day technologies, such as smartphones and flat-panel TVs. Still, it comes with a few drawbacks like performance limitations due to limited carrier mobility. Provoking the researchers in search of something better. As a result, Organic thin-film transistors (OTFTs) were developed. OTFTs have solved the problem with carrier mobility to

Electronics News Updates / By

When I started to deal with Chinese electronics suppliers from websites like Alibaba, Aliexpressand Taobao, I discovered that there are huge amount of undiscovered tools from the Chinese market. They are not easily discovered, maybe due to the Chinese language barrier, especially when we deal with a Chinese website like Taobao or maybe because most of us are

Transistors- The 70-year-old invention that changed the world

Electronics News Updates / By

Its been 70 years since the fundamental building block of electronics was created, and it has been getting smaller, and better since then. The invention that won the Nobel prize for John Bardeen, Walter Brattain, and William Shockley in 1956 revolutionized electronics and made it into the IEEE milestone list. Before 1947 computers used vacuum
