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 ...
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 ...
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 ...
Microprocessors in smartphones, computers, and data centers process information by manipulating electrons through solid semiconductors, but our brains have a different system. They rely on the ...
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 ...
