A major current law has been rewritten thanks to the three-port transistor laser. Data the transistor laser generated did not fit neatly within established circuit laws governing electrical currents, ...

Researchers have developed a single-atom transistor, the world's smallest. This quantum electronics component switches electrical current by controlled repositioning of a single atom, now also in the ...

Explains the principles of transistor switching circuits, highlighting their role in electronic computers. It contrasts transistors with vacuum tubes, emphasizing that transistors function as ...

In the late 1990s I was working for a company that manufactures sub-systems for tramways, subways and light rail car manufacturers. One day my boss tells me that one of our inverters, a 5 kW DC to ...

LM317 is one of the most popular adjustable regulator chips. The output voltage of the regulator can be adjusted from 1.25V to 35V. However, the chip can deliver currents up to 1.5A which is not ...

Last time we looked at Spice models of a current sink. We didn’t look at some of the problems involved with a simple sink, and for many practical applications, they are perfectly adequate. However, ...

A transistor is a tiny but powerful electronic component that acts like a switch or an amplifier. It is made from a semiconductor material, usually silicon, and has three legs for connection to ...

There are many cases where a power supply needs an internal current-limiter function, usually built using a current sensor, a control circuit, and a pass transistor. The current sensor itself can be a ...
