The goal of this series is to maximize the voltage gain of the single transistor amplifier. I had always thought that hFE had a profound effect upon voltage gain, so I set out to determine how ...

Researchers from the University of California – Riverside and Rice University have made the first single-transistor amplifier from graphene. The device is better than conventional amplifiers thanks to ...

Graphene has already brought us the world's smallest transistor – twice – and now the one atom thick form of carbon that recently won its discoverers the Nobel Prize has been used to create a ...

Research that capitalizes on the wide-ranging capabilities of graphene could lead to circuit applications that are far more compact and versatile than what is now feasible with silicon-based ...

US researchers have built and tested a graphene amplifier that could improve future Bluetooth, radiofrequency identification (RFID) and other wireless devices. The team claimed to be the first to ...

Graphene has already brought us the world’s smallest transistor, a triple-mode, single transistor amplifier and a supercapacitor that can store as much energy as a battery while recharging in seconds.

(Nanowerk Spotlight) Transistors are the fundamental building blocks of modern electronic devices. Depending on whether they are used to amplify or switch electronic signals they can be grouped into ...

Scientists have achieved a twentyfold amplification of single-photon signals with the help of an ultracold quantum gas. Data transmission over long distances usually utilizes optical techniques via ...

It may not be to everyone's taste, but this brand new monobloc amplifier from McIntosh cleverly blends both vacuum tube and solid-state technology in one chassis. If you’re not a serious audiophile ...

There is so much to learn about the single-transistor amplifier, that this brief tutorial hardly scratches the surface. This discussion considers only the common-emitter configuration as applied to ...
