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 ...

Most often ultrasonic transducers are used for distance measurements, and in the DIY world, usually as a way for robots to detect obstacles. But for a weekend project, [Vinod.S] took the ultrasonic ...

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 ...

Researchers have built working transistors from graphene nanoribbons less than a nanometer wide, achieving room-temperature ...

The circuit was designed to be able to obtain signals via amplitude modulation where the sensitivity and selectivity is fairly good. Amplitude Modulation AM – a method of emphasizing data on an ...

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 ...

Scientists have successfully demonstrated a microwave signal mixer made from a tunnel-junction transistor laser. Development of the device brings researchers a big step closer to higher speed ...
