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 ...

The circuit was constructed around the functionality of a Class A amplifier to create a headphone circuit. BC308 – an epitaxial planar PNP transistor used for general purpose and low noise amplifier ...

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 ...

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 ...

(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 ...

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 ...

Reading an article about the first transistorized Hi-Fi amplifier, [Netzener] got the itch to make one. But what to use for the starting point? Enter an old Radio Shack P-Box stereo amplifier kit.

I am looking at building a ~80W class A amp for experiance and to save costs. I am looking at the AE Aegis One's (nice kit for about $500 here) to couple it with for now but eventually will go up to ...

(Nanowerk News) Data transmission over long distances usually utilizes optical techniques via glass fibres – this ensures high speed transmission combined with low power dissipation of the signal. For ...
