Many applications require a circuit to perform pulse modulation and voltage amplification to drive a load with a train of impulses. A typical application is driving a piezoelectric generator in a ...

In modern communication systems, modulation is a key function that embeds the baseband signal (information) into a carrier wave so that it can be successfully broadcasted through a medium such as air ...

The circuit was designed to produce a 500mW output power transmitter whose signal modulated by FM using four transistors. Transmitter – an electronic device that can produce or amplify a carrier wave ...

The smaller electronic components become, the more complex their manufacture becomes. This has been a major problem for the ...

MIT researchers with colleagues from the University of Chemistry and Technology in Prague have used 2D CrSBr, a van der Waals ...

As with many inventions, two people had the idea for an integrated circuit at almost the same time. Transistors had become commonplace in everything from radios to phones to computers, and now ...

Transistors, the building blocks of modern electronics, are typically made of silicon. Because it's a semiconductor, this material can control the flow of electricity in a circuit. But silicon has ...

Researchers previously reported a self-aligned technique for making graphene transistors with unparalleled speed, but scalability was a question. The team now uses a dielectrophoresis assembly ...

FN, Fowler–Nordheim tunnelling; DT, direct tunnelling. Editor’s summary The ultimate in electronic device miniaturization would be the creation of circuit elements consisting of an individual molecule ...

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