Recent developments in IGBT and FWD (free wheeling diode) devices are enabling designers to achieve higher switching performance, lower electrical losses, and higher temperature operation in high ...

The word “ideal” is often used in introductory engineering classes as a starting point to describe a component. However, at some point in any actual project or design, reality sets in, as there’s no ...

Range finders are used for a wide range of tasks, from measuring the distance to an object a few feet away to the distance between the moon and the earth. They work by sending a group of energy pulses ...

Anyone who has just spent several thousand pounds on a semiconductor laser diode should think twice before simply connecting it to a conventional laboratory power supply. To avoid damaging your laser ...

Metal-insulator-metal (MIM) diodes might just be the technology that allows electronics achieve the next big leap in processing speed. Research into diode design conducted at the Oregon State ...

Researchers have invented a new organic polymer tunnel diode -- an electronic component that could one day lead to plastic computer memory and plastic logic circuits on computer chips. Today, computer ...

Oclaro, a tier-one provider and innovator of laser solutions and optical communications technologies, has announced that its laser diodes have been designed into the industry's first 15 kilowatt (kW) ...

Engineers at Sandia National Laboratories have developed a small electronic device that can siphon off excess electricity and send it to ground in just a few billionths of a second while operating at ...

A team of physicists at MIPT has offered a new design of a spin diode, placing the device between two kinds of antiferromagnetic materials. By adjusting the orientation of their antiferromagnetic axes ...

This Design Idea has proved as useful as it is simple. With just three or four components, it allows the monitoring of current from microamps to well over 100mA in a single range. I was developing a ...
