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 ...

A new technical paper titled “Three-to-one analog signal modulation with a single back-bias-controlled reconfigurable transistor” was published by researchers at NaMLab gGmbH, GlobalFoundries, and TU ...

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 ...

The transistor reactance modulator shown in the Figure is to be used in an FM transmitter. The input resistance of the transistor is 600 Ω and beta transistor is 65. (a) How much capacitance does this ...

Announced yesterday, researchers from Surrey and Cambridge universities and the National Research Institute in Rome have used thin-film source-gated transistor (SGT) to create compact analogue circuit ...

A new technical paper titled “Reconfigurable signal modulation in a ferroelectric tunnel field-effect transistor” was published by researchers at Lund University in Sweden. “Reconfigurable transistors ...

Scanning electron microscope image (false color) illustrating a full pattern of the devices. The whole structure was defined on an oxidised Si wafer. The yellow regions show portions of the ...

(Nanowerk Spotlight) Negative differential resistance (NDR), which describes a decrease in electrical current as the applied bias increases, has always been one of the hottest topics in solid-state ...

Researchers at Linköping University and the KTH Royal Institute of Technology have developed the world’s first transistor made of wood. Their study, published in the journal PNAS, paves the way for ...

Researchers in Sweden have created electronic circuits and devices that are integrated within living plant material. The team introduced a conductive polymer into the vascular system of plants, which ...
