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 ...

Atomic-scale imperfections in graphene transistors generate unique wireless fingerprints that cannot be copied or predicted, ...

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 ...

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 ...

In Parts 1, 2, and 3 we took a closer look at calculating “ac” gain and how to desensitize the circuit to temperature and transistor parameter variations. In part 4 we consider the effects of a ...

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, ...

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